But can you handle the additional cards they get? Remember, if you are the annoying one, they'll hit you first with those cards. Olli has a Standstill deck but he couples it with [[Arcane Laboratory]], which not just also annoying, it's a deadly combo. And games are horrible. Anyway, Standstill without backup doesn't do good.

Oh and it wouldn't hurt to add an additional copy of the Leyline - it's crucial for the deck and although you have have some filter cards you might end up getting it too late or not at all.

More thoughts: The Bazaar actually WANTS cards in the graveyard in order to work. So, maybe, it's better to mill than to exile cards. Also, while Elixir of Immortality is usually a very good card, it is maybe counterproductive in here. See. of you have a Counterspell in your graveyard, nobody can play a Counterspell anymore. Then again, there are so many cards, that it is highly unlikely that anybody else has the same cards as you, even of they are good ones that are typically played. So maybe keep the Elixir.
But it you have a favourite mill card, consider replacing the Cap with it. Because most players will have multiples of the same card in their deck. So, if you mill a card, nobody can play it anymore. That's better than currently where they can play their first copy without problems.
[[Cellar Door]] is a harmless/slow mill card that also provides you tokens to block attacks.
[[Keening Stone]] is a brutal mill card that does nothing else. It's a true win condition in this deck and nasty with Bazaar.
[[Jace's Mindseeker]] is a combination of mill and [[Grinning Totem]], essentially you mill for 5, play one of them and you also got a 4/4 flyer.

[[Sol Ring]] is missing.

EDIT:
I don't know why the link tag for the Mindseeker doesn't work, the spelling is correct.

Don't forget the best of all multiplayer counterspells: [[Insidious Will]]. It's a counterspell, Fork or Deflection, whatever you need. All three options are annoying and therefore should be in this deck^^

[[Clever Impersonator]] should probably also be in here, gives you so many options.

If you have one, [[Karakas]] should be in. With Leyline, this is a monster.

[[Rhystic Study]] instead of Opportunity should also add more annoyance :)

Main problem would be that can't do much about creature based decks early on. One of my favourite cards and "secret weapon" (so secret I have bought a playset but never used them so far) is [[Portal Mage]]. I guess you'll love him, too.

No, rather replace the Terrain Generator with a Mountain. Don't go below 22 land, your deck is more expensive now than the original build.

Yeah, about that - sometimes you commented on my decks and tried to squeeze in random mill cards even though the deck doesn't mill at all. But the one deck I have that DOES mill never got a comment of yours. That was always odd for me.

Yeah, I got that, given this is my ReapLace deck ... but I thought there was something particular or why did you write that message?

May I suggest [[Ordeal of Thassa]] for carddraw? It's not the best but I think it's an interesting concept, works great with the Sliths and Skulkers but can also be used to make the others stronger.
What I liked about Mirror Golem is that we had artifact creatures. What about [[Psychosis Crawler]] instead?

Just seeing this now, I wasn't active back then.
So, what did you talk about then?

Or [[turntimber Grove]] - which is what I actually meant.

Oh, I confused the golems with [[Duplicant]] so the milling is ... kindof ... justified. But I still thing these decks shouldn't be overloaded with partial themes that just don't do much. For example one of the many things green does is poison, but you didn't add a few creatures with poison because that would not be enough to ever make a kill.

I also didn't realized that the tokens from the Stalker have islandwalk, so again, the Spreading Seas do have their place now. With four Skulkers I can see this as a path to victory now.

Windfall isn't banned (in Vintage), it's restricted and you had 2 of them. Removing one of them would have been sufficient.

EDIT:
But wait - Mirror Golem gets protection from - an ability that we didn't want for beginners. Also, since all decks are mono color, you don't really need that extra mill to go for different options.

Again, a low creature count. And 4 them self destruct at end of turn while another 2 can be prevented to enter play. Ball Lighting is an iconic card but in a beginner's deck it should only be added once you have about 20 solid creatures.
See, when you put all your decks against each other, I don't see proper creature battles happening because most of them have so few creatures, blue isn't interested in creature fights, green only has manaelves, skips midranged and then deploys a single fatty or overruns within one turn, black relies on unblockables ...
I really think you'd be better off including creatures like [[Flametongue Kavu]] - that guy represents red very well and is also very iconic, but it will just generate better games with back and forth. I am also baffled that you managed to make a mono read beginner's deck without a single goblin ... [[Mogg Maniac]] is and interesting one with lots of flavour. I am also surprised that there is not a single dragon ... I think [[Demanding Dragon]] would fit the theme with the Devils and Browbeats.

Vandalblast is a bit out of place here, since all decks have so few artifacts, the overload will probably never be used. Maybe use [[Scrap]] instead, it has cycling (the new [[Shredded Sails]] is better in every aspect but the amount of options might be overwhelming). [[Violent Impact]] is also possible.

12 direct damage instants is too much for my taste. It's not enough for a pure burn deck (which I would not recommend) but enough to make the deck dependant on it --- and to make games boring. Again, the low creature count of all decks means that any game with the red deck will have empty boards for most of the game. Instead of 4 "bolt" types of instants I would only run 2 plus a sorcery x-spell ([[Rolling Thunder]]??) and then make room for something else.

Wild Ricochet will give beginners headaches understanding the rules. At some point they have to learn them anyway and the blue deck has Unsummon, so you will run into stacks with more than one effect anyway ... so this is a hard call. Maybe reduce it to [[Fork]], that will be half the trouble with timing issues.

Seems like you can't decide which card to use as your reset button. But whatever you do, don't add anything like Jokulhaups that also destroys all lands. Maybe [[Chain Reaction]] is sufficient.

Seems to be the most solid deck so far. But I do think the deck has too many manaelves and way too few fatties to go with it. In fact the deck has a single true one, Pelakka Worm, plus Gigantomancer, a card that I don't recommend for beginners. I mean, you have more ways to tutor for fatties than fatties^^
There is an abundance of fatties to choose from, I don't think you need council on that (and Muktol did that already).
But I would also add some midrange creatures. See, beginners should first learn how "normal" decks work. This being green it's of course natural to introduce mana acceleration, but if you do it like this - just cheap mana acceleration, then nothing and then fatties and Overrun, then you limited the experience to a certain archetype. And the games will probably be lopsided and dependant on the draw. So would certainly remove more manaelves or other cards to make room for some midrange creatures like the Master of the Hunt that you already have. Maybe something that is less wordy. Something like [[Kessig Recluse]], [[Crested Herdcaller]] or [[Timbermaw Larva]]. Not necessarily those.

Font of Fertility is kindof redundant and pointless here, it's main use is to fetch the right basic land, bu you have only Forests anyway. This is a creature slot in my book.

As with Protection From, I think Indestructible is a mechanic hard to understand - for example why does it not work on exile or -1 counters? But at least, in this case, the problematic situattions will not occur with the current decks as far as I remember. So, Withstand Death might be okay to add.

While I like the idea of adding a few nonbasics, I doubt Blighted Woodland is the right choice. It will be hard to calculate for a beginner when or if at all is the right time to use it. And I think even after cutting some manaelves we still have more than enough mana ramp. What about [[Khalni Garden]] instead?

Hm, this deck is all over the place.
What are the Thought Scours for? They are the only cards that mill and I don't see any combo with milling, so what's the deal?
Same for Spreading Seas, there is not a single card in here that requires the opponent to have Islands, so ...?
Then you have 2 Elixir of Immortality. That's fine, but at this point you are immune to running out of cards and can constantly reshuffle. So, what's the Learn from the Past for?
Then, again, you have a very low creature count. Blue might be the right colour to do this but I don't see an active path to victory otherwise. Or is this deck supposed to win by running the opponent out of cards with just 4 tiny mill cards and just outlasting him? If so, Chasm Skulker and the Slith should be defensive creatures. But I really don't see why a newbie should begin his career with this concept ...

So, for now, I can't really make suggestions because I don't know what this deck is trying to do. All I can say for now is that it obviously should get rid of the excess Blighted Cararact and that Windfall is restricted and the reason why this deck is not legal in any format.

But he as already enchantments that grant flying.
Since Brave the Elements was a one-time-use ... maybe [[Blinding Light]] ?This is the closest I can get.
And if we do that, I really think we should include a few artifact creatures for all decks.

"Black does have it's share of unblockable creatures, so Dread Warlock is OK for me."
My issue was twofold: 1) it's a bit OP with the lashes 2) the machanic doesn't teach much this way - if all decks were two-colour, this would be interesting, but this way it's just a weird phrasing for "unblockable"

About Spirit mantle: Protection from Creatures is still the same mechanic we want to avoid :)

I just realized that I linked a wrong card. I wanted to suggest to replace a Bad Moon with [[Ascendant Evincar]] which is Crovax but , you know ... maybe my suggestion makes more sense now :)

Regarding Corrupt: I was thinking about something like [[Life Chisel]] because it would introduce one of blacks central themes: That you have to sacrifice something to gain something. But that card has never been reprinted and as a Legends card it is most likely not an option for you. The closest thing to that would be [[Bubbling Cauldron]] but it also has a second ability that requires a specific card, which is unfortunate.

I just finished the black deck and saw that it has an equipment. So, if you want something to push through damage, what about [[Loxodon Warhammer]] ? This also teaches that artifacts are good to add something a colour typically doesn't have (in this case trample). Depending on how unstoppable you want this to be you could also use [[Whispersilk Cloak]] but I guess that's too final.

I think this needs a lot of work!

This has an even lower creature count of just 14 but 4 Bad Moons? With not a single 1 or 2 drop? I also question all those slow land destruction cards, they will either frustrate him or his opponent and you don't want that with beginners. Your decks will also be all mono with just basic lands, so you don't even need them to get rid of special lands. Besides, land destruction has gone out of fashion, they didn't print Stone Rain type of cards for years. You also did the opposite to the white deck here - in this case you have several cards where you need to pay life but not a single one to gain life.

* I would replace one of the Bad Moons with [[Crovax the Cursed]] . That ups the creature count and adds a boss type of creature to it.
* As explained above, get rid of the LD, Desecrated Earth should go. We still need more creatures. If you want to keep the discard part of Desecrated Earth you could add any of the various specters, maybe even the iconic [[Hypnotic Specter]] (without Dark Ritual there won't be any frustrating early beating). But could also be Liliana's.
* Accordingly Polluted Dead should also be changed to something more productive. Possibilities are endless of course, at about 5 mana my inner oldschooler wants to see [[Sengir Vampire]] or [[Necrataal]] but I think a proper demon like [[Bloodgift Demon]] would do well. It doesn't hurt to have a cards that uses the upkeep and the ambigous nature of the ability can teach to see two sides of the ability (do I use it on myself to get the card or can I afford to give my opponent a card to damage him?). But, since we are talking about a playset here, maybe [[Ashen Ghoul]] ?
* While reanimation is of course a main theme of black I don't think it should be Rise from the Grave because that thing costs 5 which is equal to or more than any creature it could revive! Yes, it can get opponent's creatures as well, but ... why not use good ol [[Animate Dead]] instead? This would also give white an opportunity to make use of their enchantment removal.
* Stealing creatures isn't exactly black's turf, which is why I would cut Enslave. We still need some more creatures and don't have any 1 or 2 drops. We also don't have any regenerators or deathtouchers, both of which black is famous for. [[Gifted Aetherborn]] would also add some much needed lifegain and would give the opponent something to think about when making blocking descisions. My pick for a regenerator would be [[Slith Bloodletter]] - it can be a straight regenerating blocker but also has the potential to become bigger if he attacks - and the opponent has to calculate if it's okay to waste a blocker on something that won't die anyway. These are descisions beginners can make without overwhelming them.

Additionally:
* Dread Warlock is just unblockable in this setting unless the blue deck has colour changers or the remaining decks have artifact creatures. Haven't checked blue, green and red yet but if they are of similar structure, they won't. I am not sure if that means the Warlock should be replaced or that the others should get artifact creatures. But if this stays unblockable (which is more of a blue thing again), then this is problematic with those 3 Nightmare Lashs ...
* Again, a tiny amount of non-basics to introduce the concept. Something like [[Quicksand]] maybe.
* Life's Finale ... I guess you probably want one big sweeper per deck, right? Problem with this one is that the second part of it is next to useless with the exception of those two Rise from the Grave(/Animate Dead). [[Decree of Pain]] ?
