Wisel, Empereur Meklord SP13-FR047

Neither Normally Summoned nor Placeable. Only Specially Summoned by its own effect and not Specially Summoned otherwise. When a face-up monster you control is destroyed by a card effect and sent to the Graveyard (except during the Damage Step), you can Special Summon this card from your hand. The other monsters you control cannot declare an attack. Once per turn, you can target 1 Synchro Monster your opponent controls, equip the target to this card. This card gains ATK equal to the sum of the ATK of the monsters equipped to it by this effect. Once per turn, during either player's turn, when your opponent activates a Spell Card, you can negate the activation, and if you do, destroy it.
