Kangaskhan

At the beginning of each player's upkeep, untap
Kangaskhan.
Protection from Spirits, Kangaskhan can block,
target and deal damage to Spirits with protection
as if they didn't have protection.
Enrage —Whenever Kangaskhan is dealt damage,
it gets +2/+2 and gains trample until end of turn. Detain any creatures dealt damage by Kangaskhan
during that turn. (Until your next turn, that
permanent can't attack or block and its activated abilities can't be activated.)
