Whenever you cast your second spell each turn, choose one — • Create two 1/1 white Human Soldier creature tokens. • Put a +1/+1 counter on each creature you control.

When this creature enters, until end of turn, another target creature you control gets +2/+0 and gains "When this creature dies, return it to the battlefield tapped under its owner's control." Warp 1B (You may cast this card from your hand for its warp cost. Exile this creature at the beginning of the next end step, then you may cast it from exile on a later turn.)

Whenever you sacrifice another creature or artifact, put a +1/+1 counter on this creature.

(T: Add U or B.) As this land enters, you may pay 2 life. If you don't, it enters tapped.

Whenever Haliya or another creature or artifact you control enters, you gain 1 life. At the beginning of your end step, draw a card if you've gained 3 or more life this turn. Warp W (You may cast this card from your hand for its warp cost. Exile this creature at the beginning of the next end step, then you may cast it from exile on a later turn.)

Enchant artifact or creature you control The first time you would create one or more tokens each turn, you may instead create that many tokens that are copies of enchanted permanent.

Void — At the beginning of your end step, if a nonland permanent left the battlefield this turn or a spell was warped this turn, you draw a card and lose 1 life.

Flying, lifelink If one or more tokens would be created under your control, twice that many of those tokens are created instead. Warp 1W (You may cast this card from your hand for its warp cost. Exile this creature at the beginning of the next end step, then you may cast it from exile on a later turn.)
