These are the Cards that can Fusion Summon a Monster. You can then use De-Fusion after you attack with the Fusion Monster to Special Summon the Fusion Material Monsters since it's a Quick-Play Spell Card. You can then attack using those Special Summoned monsters for potential OTK.
Elemental Hero cards focuses on Fusion Monsters. It would be nice to pair De-Fusion with it for additional Firepower.
