Penguin Squire

Cannot be used as Synchro Material, except for the Synchro Summon of a WATER monster. If a monster is Set on your field (except during the Damage Step): You can Special Summon this card from your hand, then you can reduce its Level by 1 or 2. You can target 1 face-down Defense Position monster you control; change it to face-up Defense Position, and if you do, its effects are negated unless it is a "Penguin" monster. You can only use each effect of "Penguin Squire" once per turn.
