Sub-Zero

Whenever an opponent discards 1 or more cards
for the first time each turn, put a stun counter on
a target creature.
{s}{w},{s}{u},{t}: Abilities of target creature can't
be activated this turn.
{2},{s}{w},{s}{u}: Sub-Zero gains Hexproof until
the end of turn. When you pay this cost, you may
pay an additional {1}; if you do, put a Shield
counter on Sub-Zero.
