effect:
1 Tuner + 1 or more non-Tuner monsters
Once per turn: You can target 1 face-up monster your opponent controls; its ATK becomes half its original ATK until the end of this turn. If this card in your possession is destroyed by an opponent's card (by battle or card effect) and sent to your Graveyard: You can banish 1 other WATER monster from your Graveyard; Special Summon this card, and if you do, it is treated as a Tuner.
