- Use "Future Fusion" to send 7 "Crystal Beast" monsters from your Deck to the Graveyard to set up for the Summoning of "Rainbow Dragon" (and "Rainbow Dark Dragon", if "Advanced Dark" is on the field or "Rainbow Gravity" is used). If "Future Fusion" leaves the field before this card is Summoned (but after sending the materials to the GY), you can still Tribute that "Rainbow Dragon"/"Rainbow Dark Dragon", or use "Dragon's Mirror", to Summon this card.
- "Dragon's Mirror" can especially be used to summon this card if all "Ultimate Crystal God" monsters in your hand have been Special Summoned after the second effect of "Future Fusion" resolves, easily putting over 8000 damage on the field just from activating "Future Fusion", as "Rainbow Dragon" and "Rainbow Dark Dragon" are not restricted to being Special Summoned once per turn.
- After Fusion Summoning one "Rainbow Overdragon" (typically by using "Ultimate Crystal Magic"), you can activate "Rainbow Overdragon"'s second ability to shuffle the entire field into the Deck. This leaves the opponent completely defenseless, and you have a full set of 7 Crystal Beasts still sitting in the Graveyard, letting you follow up with "Dragon's Mirror" to summon a second "Rainbow Overdragon" and attack with impunity for 4000 damage. Your opponent will also struggle to play around a Fusion Summoned "Rainbow Overdragon" as its field-shuffling ability is a Quick Effect.
