Trek to the Meditation Realm

Creatures you control have exploit.
Noncreature spells you cast have bargain.
Whenever a creature you control exploits a
creature or a spell you cast is bargained, put
a +1/+1 counter on each creature you control.
(When a creature you control with exploit
enters, you may sacrifice a creature. When you
cast a spell with bargain, you may sacrifice an
artifact, enchantment, or token.)
