Kami, Turncoat Tyrant

Creatures you control have Rend.
You may play lands and cast spells with Rend counters on them.
Whenever you cast a spell from exile, if you own
it, create Kaze, a Legendary 0/1 demon token
with haste. If you do not own the spell, until end
of turn, target creature you control gains Fear
and +X/0, where X is the number of cards exiled
this turn.
