Jaata Snov, Endless Frost

Jaata's Toughness is equal to the number of
Snow Permanents you control.
Tap an untapped Snow permanent you control:
Tap a permanent that shares a type with it.
When a permanent an opponent controls is
tapped by a spell or ability you control,
put a stun counter on that permanent.
(If a permanent with a stun counter would
become untapped, remove one from it instead.)
