While the search is great on Urza's Saga, it only tapping for colourless and the token being useless, in a deck with such heavy pip requirements for how low the actual land count is. And it only searches out a Mishra's Bauble mainboard. I admit that filtering out the deck is part of the gameplan for a deck like this, but Saga is a little too specific in what it does to slot in here.
And yeah, it does help find the Tormod's Crypt, but that's a very specific scenario that I'd need, and there are a lot of situations where I see myself searching for it with the Saga the turn after an opponent Delves into a Murktide or has already scammed me out of my hand.

Mutktide is the most obvious answer. Other than that, it's arguable that either Fury or Subtlety were cut since I see them a lot in the deck lists for Murktide.

But I wouldn't say that anything was necessarily cut. I added the Kiki/Exarch combo first, then looked at a couple of Murktide decks and went off my experience versing them, and just added their greatest hits like Expressive Iteration, Mishra's Bauble and DRC. Kept going until the deck was done! Well, I was kinda stuck towards the end until I remembered that Preordain got unbanned and is a Sorcery, so better chances getting Delerium instead of going with Brainstorm.

Part of the reason that I decided to go with Grief in that deck though, is that the Evoke cost is actually an advantage to me, considering Ashiok is the endgame and requires my own cards in exile.
As for Gutshot, I don't own any. And my local doesn't have any either.

Painter's Servant could be an interesting colour-hate deck, if you can find a way to consistently keep it alive and avoid cards like Fury. But there are quite a few white decks that just run cards like Paladin En-Vec to just avoid them.

Yeah, this game is incredibly busted. Not according to WotC though, since we all saw the last banlist (or lack there-of) recently.

But this is why I am trying to make a deck specifically designed to spite the main types of decks being played and largely exploited in Modern currently. I haven't got all the cards, or time, to test it all out, but the theory is there for now. That being said, I could always use some advice when attempting this sort of thing.

With how I roll for my Warp Lightning Cannons? That's a good one.
If any of them make it past turn 2, then it's a good game for them. And out of the 20 I've used, about 3 have been taken out by enemies.

Only free spell that I see regularly is Mishra's Bauble, but that is mainly in Murktide decks because of how easy it is to proc Delirium with for cards like Dragon's Rage Channeller. Most of the cards I see these days are 1-3 drops. Or have ways of being cheated in, like Foothills Cascade.
There is also the Beanstalk deck that plays a lot of big cards, but that also has heaps of ramp.

That's a good question! I think the thing is with the Leyline cards is that for them to be effective against cards like Grief with how fast Modern is, they have to be in your opening hand, and people aren't willing to mulligan down to find an out that MAY help them against a deck. The Leyline cards being 4-drops in a format ruled by 1-3 drop cards, or ways to cheat out bigger cost cards, is also a liability for some people considering they are essentially defensive passives. Leyline of Sanctity is also white, which is the least played colour in Modern if the stats I've seen are anything to go by.
A lot of my "Sample hands" that I would keep don't even have LotV in hand, because the Scam element is just too strong to pass up. Exiling a Tombstalker to double-Grief turn one seems potent enough to hold onto, even if there is the chance of being hit by the same sort of play.

I also don't recall a lot of cards that can be played from exile, and the ones I do have a hefty cost, such as Skaab Ruinator requiring 3 creatures in grave to exile, or a sphinx with a very high mana cost.

I'm also unfamiliar with the counterspell you have mentioned here. It does seem a bit niche unless cards like Force of Will or Force of Negation are everywhere too amongst blue decks.

I think that nobody owns the borderposts and it's the fact that they enter tapped, while setting you back on a land drop. I do have the red/black one (Veinfire?) and use it in my Obosh deck. It isn't a terrible card in there, but doesn't feel as good as a Rakdos Keyrune.

"One of the oldest" being more along the lines of the one that everyone learns of first, or at least within the first 3 infinite combos.
If we're going purely off MtG release dates, then yeah. It probably isn't THAT old. But that isn't what I meant by "oldest".

So, how's the rest of the deck looking anyway?

I'm a little surprised that some of what can be considered the all time cEDH staples, such as Rhystic Study, are not in here. Or an infinite combo that I could see either.
I would have gone for a Grapeshot or Brain Freeze too as an instant game ending card with how this deck is designed.

Overall, interested to see this deck play. Good job!

Huh. I didn't know that!
But I also thought that gris was French for grey. I work in liquor retail, and the variety known as Pinot Gris is decently popular in my area.

Yeah, Spider Spawning is too expensive for this deck and doesn't outright win the game when played. It'd be great for an EDH version of this deck though!

And Caustic Caterpillar seems like a good SB option, but I don't know how prevalent artifacts or enchantments are in Modern atm. The only deck that I really know of being super prevalent is Rakdos Scam.

Not that well known, apparently. And the important part was "how I think it does", which yes. It does.

Just putting it out there, that bit when making a deck labelled [DESCRIPTION] is great for this sort of thing!

IF it works how I think it does, then I would recommend a way to either have Grape Shot or Brain Freeze in there as either an alternate or backup to Impact Tremors.

Might want to include cards like Slip Out the Back or Planar Incursion, as they pair really nicely with cards like Fury.
Yeah, I know that this isn't a Scam deck, but it is a really strong combo to consider!

If I had to pick a card to replace in this instance, I'd say Release to the Wind. Yeah, it's only a flicker instead of full exile, but it's cheaper.

That's a great idea! I'll take out Phyrexian Arena for it, since I could just let more things die to Blitz and draw cards that way.

Thanks, mate!
I find personally that a good description actually helps people understand your decks more easily by explaining the thought process. Back when I was known as s0rinmark0v and made by anti-token token deck, I doubt many people would have understood why I included Illness in the Ranks as it is anti-synergy with Tokens, so having that in there really helped people understand the vision!

I see what you did there.
Nice.

Huh. I missed that banning.
I mostly play Commander these days.

So, looking at this deck, I can kinda see why you're interested in using Skred as your big finisher. Issue I have in general is that it is a slow process in mono-red, as you have no ways of actually searching out lands and putting them onto the battlefield quickly enough to really ramp that Skred damage, besides an actual land.
BUT without changing your entire deck to Red/Green and rebuilding it as a ramp deck, here's some notes on the cards you're not a fan of:

Karn, the Great Creator - This card is not great for your deck, unless you're heavily relying on that -2 to fetch cards from your sideboard. But if you wanted to really abuse that passive, add in the card Mycosynth Lattice! It literally shuts down your opponent since EVERYTHING is now an artifact, and your opponent cannot use them. If I had to pick a card to replace from the SB, I'd have to go with Walking Ballista. Yeah, it's an absolutely devastating finisher, but that requires you to have already ramped heaps.

Boros Reckoner - It's a decent deterrent tool, like Phyrexian Obliterator. I think it's fine in any sort of burn deck.

Chandra, Acolyte of Flame - She's actually a good fit for your deck! If the goal besides Skred is red Superfriends, comboing with Sarkhan to give everyone more counters, I'd run more of her! I'd drop a Mind Stone and maybe a Relic of Progenitus to add another copy or two of her. It's always a good idea to have a backup plan, because if you use an early Skred, or it's countered, and someone has a card like Surgical Extraction, there goes your entire deck.

Koth of the Hammer - I know that you didn't mention this one, but I think it needed mentioning. If you swamp Hammer for Fire of the Resistance, then it'll add more of that ramp to find more snow lands. Same mana cost, but fetches lands instead of transforming them, so they can't be killed off like a creature and fuel Skred faster too! Just worth considering. Ult/Emblem is a side-grade, but main ability is a boost.

Hope that helps!
