- This card can be summoned as early as the first turn if your hand contains "Union Hangar" and "XYZ Combine".
- This card's Fusion Materials can be searched by "Single Purchase", "Temple of the Kings", "Rescue Ferret", "Transmodify", "Downbeat", "Ties of the Brethren", "Number 29: Mannequin Cat", "Soul Rope", "Resonator Engine", "Painful Escape", "Vampire Dragon", "Summoner Monk", "Dragunity Corsesca", "Chaos Zone", "Machina Armored Unit", "Gear Gigant X", "Heavy Armored Train Ironwolf", "Jade Knight", "Photon Veil", "Cyber Repair Plant", "Fusion Conscription", "Fusion Reserve", and "Ojamassimilation".
- "Y-Dragon Head" and "Z-Metal Tank" can also be searched by "Sangan", "Broken Blocker", "Machina Peacekeeper", "B-Buster Drake", "Union Hangar" and "Unauthorized Reactivation".
- The discard cost of "XYZ-Dragon Cannon" can be eased with "Ojamagic" and/or "Night Assailant". "Elemental HERO Woodsman" can also help with the discard cost (although it's limited to using its effect once per turn).
- Use "Forced Requisition" to destroy 2 cards (one in your opponent's hand and one on the field) for each card that was discarded.
- "Union Scramble" can be used to summon all three Fusion Materials from banishment, though all will need to be protected until your next turn in order to summon another copy of this card.
