Corwinnn, Defender of Nut

Defender
Forecast—{w}{g}, Reveal Corwinnn from your
hand: Put an acorn counter on each of up to
two target creatures.
When Corwinnn enters the battlfield,
detain each creature with an acorn counter
on it until Corwinnn leaves the battlefield.
I will defend the nuts at all costs, because a world
without nuts is a world damned to Hell
