Power Bond [RYMP-EN062] Common

Send, from your hand or your side of the field to the Graveyard, Fusion Material Monsters that are listed on a Machine-Type Fusion Monster Card, then Special Summon that Fusion Monster from your Extra Deck, and it gains ATK equal to its original ATK. (This Special Summon is treated as a Fusion Summon.) During the End Phase of this turn, the player who activated this card takes damage equal to the original ATK of the monster (at the time it was Summoned).
