Made this deck at home initially, and kept thinking I would make another which would counter it. 5 decks later I couldn't find one. Insanely fast ramp, mid-game, and amazing sustain. Avacyn resistant, but she would be worth holding on to a Grasp of Darkness for.
Talk-through:
Grasp of Darkness Duh, Avacyn.
Deathcap Cultivator Quick and easy way to get that extra mana for turn 3
collective company
and a good late-game blocker with its deathtouch.
Rot Shambler Don't knock this guy...After a token sac to flip the Westvale Abbey
this guy is a 6/6 escourt at the least.
Catacomb Sifter Easy pick for its 3 mana cost, power/toughness, extra 1/1 token, AND a scry each time one of your units dies.
Inexorable Blob This guy isn't great for much except keeping pressure on your opponent. Maybe replace this, but I don't know with what
To the Slaughter An instant removal for that one guy left, or a tough choice for your opponent. Delirium makes it awesome against most combo decks
Vampiric Rites Great card for 1 mana. Gives you control against removal I can't pass up, and a way to cycle through some tokens for a better hand. (also remember the scry you may have with Catacomb Sifter).
Hangarback Walker Easily the most necessary card for a token deck. If your opponent tries to exile, you have your Vampiric Rites to counter that.
infinite oblitheration Best side-board card in rotation IMO.
Matter Reshaper Had to add this the deck is creature-heavy, and most are 3 mana or less.
Liliana's Indignation Easy path to delirium, and possibly the boost you need for the W.
collective company
because coco
Autumnal Gloom
Wasn't going to add this, but its ability to get delirium faster can't be underestimated, and I needed another Enchantment somewhere. Also, Matter Reshaper can get this out on the field if you draw it.
Pick the Brain A great proactive card to side-board in if you need to stop that one thing that can ruin your game. Also, delirium.
