Allright,I've been brewing this deck sind today morning and I am surprised how consistent this deck is. I did not imagine it to kill at turn 4/5 consistently, rarely at turn 6+ when gold fishing.
Creature choices which are fixed:
Kiki-Jiki, Mirror Breaker + Craterhoof Behemoth for one swing kill.
Kiki-Jiki + Worldspine Wurm for 15/15 trample token and bodys at end of turn
Single Blightsteel Colossus for occasional surprise kills.
Overgrown Battlement,
Wall of Roots
, Sylvan Cariatyd our main mana source, don't die to a bolt, can block turn 1-3
Creatures still in question :
Restoration Angel can kill in one swing with Kiki-Jiki, but not hardcastable
Wurmcoil Engine needs more testing, but I really like this guy. He protects, he has synergie with Kiki-Jiki.
Primeval Titan, not sure about this guy, needs more testing, maybe a 2 of
Hornet Queen for value, but not sure if needed. Maybe against decks with heavy removal and bounce.
Emrakul, the Aeons Torn never was able to cast him, no synergie with kiki jiki, maybe I will remove him from the deck.
Ulamog, the Infinite Gyre easier to cast than Emmy, destroys a permanent when cast vs
Ashen Rider
vs Duplicant
Elvish Mystic, Llanowar Elves not sure about these guys.
Fetchlands: not needed so far, I did testing with 10 forests and 12 fetch lands, but they didn't have any impact, deck thinning is marginal and Primeval titan should fetch all lands anyway.
