Corwinnn, Sylvan Summoner

Squirrels can't attack you or be sacrificed.
Lands you control have "{t}: Create a 1/1 green Squirrel creature token"
At the beginning of each opponent's combat
step, that player may gain control of any number
of Squirrel creature tokens you control until end
of turn. If a creature is gained control of in this
way, untap all Squirrels and put a +1/+1 on each Squirrel.
