2 WATER monsters
You can send 1 card you control to the GY; all WATER monsters you control gain 500 ATK/DEF this turn. If a WATER Link Monster(s) you control is destroyed by an opponent's card effect, while this card is in your GY (except during the Damage Step): You can banish this card, then target 1 of those destroyed monsters; Special Summon 1 WATER monster from your hand or GY, with a Level less than or equal to that monster's Link Rating. You can only use each effect of "Archidux, the Squid Sorcerer" once per turn.
