{T}: Add {C}{C}.

Whenever you cast a creature spell, create X 1/1 black Thrull creature tokens, where X is that spell's mana value. When you control seven or more Thrulls, sacrifice Endrek Sahr.

Whenever an opponent draws a card, that player may pay {2}. If the player doesn't, you create a Treasure token. (It's an artifact with "{T}, Sacrifice this token: Add one mana of any color.")

Create two 1/1 white Spirit creature tokens with flying. Flashback {1}{B} (You may cast this card from your graveyard for its flashback cost. Then exile it.)
