Buster Blaster #DT06-EN055

EarthMonster

Once per turn, during your Main Phase, you can equip this card to a monster you control as an Equip Card, OR unequip it to Special Summon this card in face-up Attack Position. While equipped to a monster by the effect, the equipped monster loses 500 ATK and DEF. If the equipped monster destroys an opponent's monster by battle, destroy all face-up monsters on the field the same Monster Type as the destroyed monster. (A monster can only be equipped with 1 Union Monster at a time. If the equipped monster would be destroyed, destroy this card instead.)
