Card Rulings:Future Fusion

TCG Rulings

 * You cannot select a Fusion Monster that can only be Special Summoned by the method written in its text, like "Gladiator Beast Heraklinos", "Elemental Hero Grand Neos", "XYZ-Dragon Cannon", or "Evil Hero Dark Gaia".


 * "Future Fusion" must remain on the field for the effect to activate. If it is not on the field during the 2nd Standby Phase, then you do not Special Summon the Fusion Monster.


 * You cannot use substitute Fusion Material Monsters such as "King of the Swamp". You must use the monsters listed on the Fusion Monster Card.


 * Sending monsters from the Deck to the Graveyard is not a cost.


 * If "Future Fusion's" activation is chained by "Mystical Space Typhoon" and it is destroyed, no monsters are sent from the Deck to the Graveyard.


 * You cannot activate "Future Fusion" if you do not have a Fusion Monster in your Extra Deck and the appropriate Fusion Material Monsters in your Main Deck.


 * Destroying the monster when "Future Fusion" is removed from the field is an effect that cannot be chained to.


 * If the Special Summoned Fusion Monster is removed from the field without being destroyed then "Future Fusion" will remain on the field meaninglessly.


 * You cannot select a Fusion Monster that has another Fusion Monster as one of its Materials, such as "Dark Flare Knight" or "Elemental Hero Shining Flare Wingman", for "Future Fusion". The Fusion Material Monsters must be sent from the Main Deck.


 * You can chain "Royal Oppression" to negate "Future Fusion" when the card is activated (placed face-up on the field).


 * "Future Fusion’s" effect counts Standby Phases, not turns, so "Pyro Clock of Destiny" would have no effect.

Mentions in other Rulings

 * Barrier Statues: You cannot activate “Future Fusion” or the effect of “Cyber-Stein” while a Barrier Statue is in play if the only Fusion Monsters in your Extra Deck have barred Attributes.


 * Chain Material: You cannot use "Chain Material's" effect when resolving "Instant Fusion" or "Future Fusion".


 * Chimeratech Overdragon: If this card is Special Summoned by the effect of "Future Fusion" while you have "Cyber Phoenix" in Attack Position, when this card's effect sends all other cards you control to the Graveyard "Future Fusion" is still being negated, so the "Chimeratech Overdragon" will not be destroyed and remains on the field.


 * Dimension Fortress Weapon: “Future Fusion” cannot be activated while “Dimension Fortress Weapon” is on the field. If “Future Fusion” is activated, and “Dimension Fortress Weapon” is Summoned in a chain, the effect of “Future Fusion” is not applied, no monsters are sent to the Graveyard, no Fusion Monster is Special Summoned, and “Future Fusion” remains on the field meaninglessly.

OCG Rulings

 * The Fusion Material Monsters are sent to the Graveyard when "Future Fusion" resolves.


 * "Future Fusion" does not target the monster in your Fusion Deck - you choose which Fusion Monster to Summon when resolving the effect. After the monster is Summoned, "Future Fusion" continuously targets the monster.


 * You cannot use Fusion Substitute Monsters, since they have no effect while in the deck.


 * "Future Fusion" must remain on the field for the effect to activate. If it is not on the field during the 2nd Standby Phase, then you do not Special Summon the Fusion Monster.


 * If "Chain Material" has been activated, when you activate "Future Fusion", you can use Monsters from your Deck/Hand/Field/Graveyard as Fusion Material Monsters.


 * If you activate "Future Fusion" and send "Jinzo" and "Jinzo - Returner" to the Graveyard to Summon "Chimeratech Overdragon", then you can activate the effect of "Jinzo - Returner" and Special Summon "Jinzo".


 * While "Koa'ki Meiru Drago" is on the field, "Future Fusion"/"Instant Fusion"/etc can still be activated, and the effect of "Cyber-Stein" can still be activated. However, when resolving the effect, you can choose neither a LIGHT nor a DARK Fusion Monster to Special Summon.  If you only have LIGHT and DARK Fusion Monsters in your Extra Deck, then you cannot activate "Future Fusion"/the effect of "Cyber-Stein"/etc.


 * If "Future Fusion" is activated and chooses a LIGHT or DARK monster and later the effect of "Koa'ki Meiru Drago" is applied, then during your second Standby Phase no monster is Special Summoned and "Future Fusion" remains on the field meaninglessly.


 * The effect of "Royal Oppression" can negate the "Future Fusion" when "Future Fusion" is first activated. However, during the second Standby Phase when the Fusion Monster is Special Summoned, you cannot activate the effect of "Royal Oppression".


 * "Future Fusion" cannot Special Summon a Fusion Monster that lists a Synchro Monster or a Fusion Monster as a Fusion Material. Thus, ":" cannot be Special Summoned by "Future Fusion".  Furthermore, when you activate "Future Fusion", you cannot choose ":" as the monster to be Special Summoned.


 * If you activate "Future Fusion" but then your second Standby Phase is skipped by "Solomon's Lawbook", then you cannot Special Summon the Fusion monster during a subsequent Standby Phase.
