Zombie Tiger [MFC-011] Common

Once per turn, during your Main Phase, if you control this monster on the field, you can equip it to your "Decayed Commander" as an Equip Spell Card, OR change it back to a monster in face-up Attack Position. When equipped to a monster by this card''s effect, that monster''s ATK/DEF is increased by 500 points, and each time it destroys 1 of your opponent''s monsters, 1 card is randomly selected from your opponent''s hand and discarded to the Graveyard. (1 monster can only be equipped with 1 Union Monster at a time. If the monster that this card is eqipped to is destroyed in battle, this card is destroyed instead.)
