Sealeo

You may sacrifice a creature named Spheal rather
than pay this spells mana cost.
Last strike, absorb 1.
Sealeo gets +0/+2, loses last strike as long as the
defending player this turn controls a snow land.
{u}, {t}: Sealeo deals damage equal to its toughness
to target creature. If the target is nonsnow and {s} was spent this way, put a stun counter on it
for each card in your hand. (If a permanent with a
stun counter would become untapped, remove one
from it instead.)
