Unfortunatly, you cannot have any other creatures other than the ones you intend to morph into, lest you hit one of the 1-drops. Only 1-drop card that gets around this rule is wind zendikon

Vins of Vastwood is the green counterspell and will keep your piper alive for the turn he needs.
However if your going to make a piper deck, pick better creatures. Iona, Progenitous, Inkwell Leviathin, Sphinx of the steel wind are all winners. Yes you cannot hard cast them, but that isn't the point of your deck is it? My advise is stall with fog + tanglesap untill you have enough mana to play piper +1 extra so you can cover it with vines or 2 extra and canopy cover it. Then let the big boys fall.

kor duelist + gorgon flail = 1st strike + deathtouch goodness. Basilik collar works as well if you have them. Overall, it looks like it moves fast and packs a hel of a punch

Yea try to get 4 of's for the important cards..

Or you can add 40 more cards and make an Edh deck though you would need a good general

I enjoy these kind of brutal decks, but it worries me that you only have a total of 6 means of getting a creature out. Here is my take on Polymorph, though I went ur instead of ug http://www.mtgvault.com/ViewDeck.aspx?DeckID=39775

Eternity Vessel.... Funny card but can backfire easily. For example; Vampire hexmage it and you lose. It does't really have a place in this deck. I would swap it out for a more powerfull vampire. Noctournus, Bloodwitch, or anowan.

-2 doom blade + 2 Tendrils. I would suggest cutting more of the 2 ofs and creature more 4 ofs. I would help more but Im tired and going to bed...

Roil Elemental maybe? It would work well with landfall and is a decent control card. Also maybe use vapor snare to keep bouncing lands and also steal your opponents baneslayer :)

Soo Grixis Cascade Control is the strongest type of Grixis deck in type 2.

Here is my advice. -4 Negate +4 Bituminous Blast. Negate is to situational and bit blast is a powerfull spell w/ cascade
-4 Seering Blaze + 4 blightning Blightning is one of the best cards in standard and and deck wth black + red should use it
-1 Island, -1 Swamp, - 1 Montain, -1 Tar pit +4 Crumpling Necropolis. Will help with mana fixing issues
Prithing needle is a side board card so id say -4 and put them in sb. Replace with +4 Kathari Remnents. Kathari is a great block tht keeps comming back and gives you a free spell. Whats not to like?
-4 Calcite Snapper Not a very good creature for what you are trying to do. +4 of any of these : Vampire Nighthawk, Great Blocker, Thraximundar A powerfull finisher, or a combination of these.

Planeswalkers are okay. You should be able to keep them alive with all of the killspells + blockers you have. If you have trouble keeping them alive, swap them or something out for unscythe Killer of Kings. +3/3 first strike and spawns blockers. You can cascade into it. I use it on vampnighthawk and make an unstopable 5/6 first strike, flying, lifelink, deathtouch machine.

Good Luck with this build, Needs some work but the only changes I'd say are necesary are Seering blaze, negate, and the land

I'd say -4 scrib nibbles +4 hypnotic spectors or nyxathid but either way I agree that there are better cards than scrib nibblers. Also I would consider splashing red so you can run spells like blightning, burning inquiry, terminate, bituminous blast ect...

No offense Vincent but just about all your points are wrong :/

The fetch lands trigger ob-nix and also reduce the amount of mana in your deck so if the game becomes a top deck fight, He will have a better chance of drawing something usefull.

Vampire Aristocrat is usless in most vampire decks but he fits amazingly well in this one considering the sacrifice a creature ability combined with the percecutor. That being said, I think there are enough methouds to kill persecutor anyway.

Sign in blood is an amazing card, black card draw is always +1. End of story

I would consider finding space for a secondary win condition though. However black isn't my color so as to that good luck ^^.

Personally, I would advice splashing red so you can utilize cards like blightning as well as lightining bolt and even shock. I have found that it is better to use direct damage spells to activate blodchief ascension then creatures.

Drop the dispel and the hindering light.
Not very good cards in general.

Replace the dispel with 4 jwari shapshifter. One of the better allies. Also 4 ondu cleric is a must and swap hindering light for them. Lastly, this is a creature oriented deck so consider putting in 4 ancient ziggurat which would work wonderds for your mana issues. Also cascade works very well with allies, Consider bitumonus blast or ardent plea, captured sunlight, bloodbraid elf or enlisted wurm.

I agree. Green and White have the best allies by far.
Swap out black for either o-ring,brave the elements, join the ranks is a must 2 allies at instant speed.
Check out some of the green allies as well.

Problem is you have nowhere to dump all of this mana that you generate. Id say drop in some antqueen's or warcallers and just abuse their abilities with all the mana locust hords away.

I like it. Warcaller is a hilarious + awsome card. You might consider finding some oren -reif the vastwood. Works nicely with warcaller and gives all of your elves alittle something something.

I like it. This build has come a long way. My last tips are for the sideboard. You have agro stopped already so i would reccomed Vampire Hexmage as an anti-planeswalker card. Also run some artifact destruction. Unfortunatly I dont have a card for that off the top of my head. Conider some discard or card draw cards, couriers capsle, divination ect. Good Luck with this deck! +1

So sideboard time.
Definatly find room for Infest or Pyroclasm do shut down any aggro build. If you are worried about friendly fire, Use marsh casualties, more mana but safer and you can still pay kicker if you cascade into it.

Another card similar to jagged-scar archer with evasion is Droves of Elves. I would consider finding space for it. Another fun token generator for elves is elvish prominade, and hunting triad. Plus there is the new world wake elf Warcaller who looks fun, especially with the perfect. And of course if you have some extra money archdruid is a winner.

The problem with deny reality is that it can cascade into something that does the job it does better.
For example the card you cascade into goes onto the stack above the affect of the spell, so say you deny reality into a bolt, You can bolt his creature but that wastes the deny reality, or you can throw the bolt at the players face but then he plays the card you bounced the next turn. While cascade is a wonderfull/broken mechanism I would still advocate finding space for terminate. It is by far the strongest kill spell in type 2 and is the only suggestion that I say is a must have in any deck that runs red and black.
