You can only activate 1 card with this card name per turn.
(1) Banish 4 “HERO” monsters from your GY and/or face-up field, then target 1 “HERO” monster in your GY; Special Summon it, ignoring its Summoning conditions, and if EARTH, WATER, FIRE, and WIND Attributes are all among the monsters you banished to activate this effect, double the Summoned monster’s original ATK, and if you do that, negate the effects of all face-up cards your opponent currently controls.
