Magistery Alchemist — Ruling

Effetto 0

• This card targets 1 "HERO" monster in your Graveyard.
• Banishing 4 "HERO" monsters from your Graveyard and/or face-up from your field is the cost to activate this card.
• This card cannot be activated during the Damage Step.
• When targeting a Special Summon-only "HERO" monster, it must be one that was sent to the Graveyard after it was properly Special Summoned. (You cannot target a Special Summon-only monster that was sent directly from the Deck or Extra Deck to the Graveyard.)
• If the monsters banished as cost to activate this card included EARTH, WATER, FIRE, and WIND-Attributes, the part of the effect that doubles the Special Summoned monster's original ATK and negates the effects all face-up cards on your opponent's field is applied. (Even in this case, Special Summoning the targeted monster is considered the last effect to resolve.)
