Whenever a creature you control deals combat damage to a player, you may sacrifice it. If you do, draw cards equal to that creature's power.

Create an 8/8 blue Kraken creature token with hexproof.
Rerun (If you cast this from your hand, exile it as it resolves. Whenever a creature you control dies, you may cast this card from exile without paying its mana cost.)

As long as you control exactly one creature, no more than one creature can attack or block each combat.

At the beginning of each end step, create X 1/1 white Spirit creature tokens with flying, where X is the number of nontoken creatures that died this turn.

Choose a creature. Exile the rest.

Flying
When Planchette Poltergeist enters, you may exile target creature. Its owner may cast it from exile for as long as it remains exiled.

Players can't sacrifice creatures to cast spells or activate abilities unless that player sacrifices an additional creature. The same is true for discarding cards and paying life.

Creatures can't attack you or planeswalkers you control unless their controller pays 2 life for each of those creatures.

Exile target creature. Return that creature to the battlefield under its owner's control at the beginning of the next end step.

Exile target creature. Search its controller's graveyard and library for any number of cards with the same name as that creature and exile them. Then that player shuffles.

Creatures can't attack or block alone.

Each creature with power greater than its toughness doesn't untap during its controller's untap step.
