Milo of the Grim Blizzard

Spend only snow mana on Milo.
Whenever a permenent becomes the target
of a spell or ability, its controller sacrifices it.
Milo of the Grim Blizzard can't be
sacrificed. Whenever a spell or ability
would cause it to, put a +1/+1, trample
counter, or menace counter on it instead.
