Icejade Erosion (BACH-EN066) [Battle of Chaos]

You can target 1 face-up card your opponent controls; destroy 1 "Icejade" monster you control, and if you do, negate the targeted card's effects until the end of this turn. If a face-up WATER monster you control leaves the field by an opponent's card, except by being destroyed (and except during the Damage Step): You can add to your hand or Special Summon, 1 "Icejade" monster from your Deck. You can only use each effect of "Icejade Erosion" once per turn.
