If a monster declares an attack: Its controller tosses a coin and calls it. If they call it wrong, negate the attack. If a monster(s) is Special Summoned: Its controller rolls a six-sided die and that face-up monster(s) loses ATK equal to the result x 200, and if the result is 1, its effects are negated. These changes last until the end of this turn. You can target 1 “Matoran” monster you control; this card’s effects cannot be activated until your next Standby Phase, also add 1 “Matoran” monster from your GY to your hand, then you can Special Summon it if the target is a WATER monster.
