Use this with Vision HERO Trinity the turn it is summoned to decrease attack by 5000 then attack with Trinity.
Summon 2 copies of this card to allow each to select the other for their effects. This allows you to drop the ATK of virtually any 2 monsters to 0. This enables "Evil HERO" and "Destiny HERO" monsters to attack and destroy them without fusing.
Unlike other "HERO" Fusion Monsters, the "Vision HERO" Fusion Monsters can be resurrected by cards such as "Monster Reborn" because they don't have the "This card cannot be Special Summoned except by Fusion Summon" clause.
