If you control a "Mikanko" monster: Target 1 face-up monster on the field; equip it with 1 Equip Spell from your Deck that can equip to it. If an Equip Spell(s) is sent to your GY, while this card is in your GY (except during the Damage Step): You can banish this card, then target 1 Equip Spell in your GY; add it to your hand. You can only use each effect of "Mikanko Rivalry" once per turn.
