- You can also Xyz Summon this card by using "Rank-Up-Magic Astral Force" on "Googly-Eyes Drum Dragon".
- This card can be Xyz Summoned with 2 "Metal Reflect Slime", 2 "Tragoedia", 2 "Exodius the Ultimate Forbidden Lord" or "Andro Sphinx" and "Sphinx Teleia" in combination with "Pyramid of Light".
- This card can be Xyz Summoned with 2 "Yubel", which can be Summoned using "Call of the Haunted"/"Limit Reverse"/"The Dark Creator" with "Inferno Reckless Summon".
- "Koitsu" can be Summoned in a similar fashion. You can Special Summon "Koitsu" with "Athena", "Limit Reverse", "Valhalla, Hall of the Fallen" or "Court of Justice", and then use "Inferno Reckless Summon" to get 2 more, then Overlay. You can also use "Roll Out!" to equip it to an "Aitsu" you control and Special Summon it by its own effect, but "Aitsu" is Level 5.
- You can Special Summon "Exodius, the Ultimate Forbidden Lord" and then Special Summon "Mirror Ladybug" to Xyz Summon this card with virtually no set-up. This can also be done with "Cyber Eltanin" instead of "Exodius", but you must have at least 1 LIGHT Machine in your Graveyard.
- You also summon this card by special summoning "Rocket Arrow Express" and "Mirror Ladybug".
- Combine this card with "Limiter Removal" for 6000 damage if attacking directly. If the attack goes through, using "Gustav Max's" effect to inflict the remaining 2000 points of damage could end the game.
- It is possible to create an OTK with 2 or more of this card, "Chain Material", "Fusion Gate" and 2 or more "Elemental HERO Electrum" in your Extra Deck with the proper Fusion Materials. See Elemental HERO Gustav Max OTK.
- You can use the effect of "Sephylon, the Ultimate Timelord" to help summon another Level 10 Fairy monster (e.g. "Metaion, the Timelord") to use as an Xyz material to summon this card.
- "Number 19: Freezadon" can be used to provide enough raw Xyz Material to deal exactly 8000 points of effect damage (over four turns).
- Use this card with "Xyz Unit" or "Xyz Territory" for a massive 2000 point ATK increase. Plus, "Xyz Unit" can provide "Gustav Max" with extra uses of its damaging effect for increased damage.
- Another good combo with this card requires 2 "Gishki Zielgigas". Their effects, if necessary, can help clear the opponent's field. Attack directly with both, for 6400 damage (3200 x2). Then, use them to Xyz Summon this card. Activate its effect for an additional 2000 damage, resulting in 8400 total damage for a possible OTK.
- This card can be easily summoned with the "Mecha Phantom Beast" monsters.
