- This card can be used similarly to "De-Fusion", removing your Neo-Space fusion monster if it is targeted by a destruction effect while still being able to re-fuse it or to gain an extra attack during the Battle Phase.
- If you don't have Neo Space on the field, you can use this card in order to fuse your monster again next turn.
- You can use this card to change one Neos fusion for another, if you happen to have a different "Neo-Spacian" on the field.
- This strategy also works with NEX if you're using this effect on Elemental Hero Aqua Neos. This is especially good if you don't have Neo Space or Instant Neo Space, because Elemental Hero Marine Neos doesn't share the common weakness of Neos fusion monsters.
- You could also use the above strategy to trade a level 7 Neos monster for a level 9 Neos fusion monster, by adding the appropriate Neo-Spacian to the second contact fusion.
- You can use this card to activate the effects of "Elemental Hero Aqua Neos", "Elemental Hero Glow Neos" or "Elemental Hero Grand Neos" twice per turn.
- This card combos nicely with Elemental Hero Air Neos as you can use its effect to gain attack points if your opponent's life points are higher then after you attack you can use this card to summon Neo-Spacian Air Hummingbird and restore your life points plus gain a few extra attacks.
- Since Neos fusions return to the fusion deck during the End Phase, if you have no way to keep the fusion monster on the field use this card to get the fusion materials back since the monster would just return to your fusion deck by it's own effect.
- This card also combos well with Instant Neo Space. If you use this on an equiped Neos fusion monster you can get back the Elemental Hero Neos You originally used for the contact fusion and one from your deck, hand or graveyard by the effect of Instant Neo Space, Becuase it doesnt say you have to target the Elemental Hero Neos You used for the contact fusion summomn. You can also play this during the battle phase to attack with the two Elemental Hero Neos you get from this combo.
- Don't forget that this card also works with Rainbow Neos and Elemental Hero Divine Neos.
- Bear in mind that if you used Elemental Hero Neos Alius and/or Elemental Hero Prisma for the contact fusion of the selected fusion monster, you will have to change their/its name(s) again.
- If you Contact Fusion Elemental Hero Neos Alius,that has it's name treated as Elemental Hero Neos,to summon a "Neos" Fusion Monster,you can use Contact Out to gain extra attack by pulling out Elemental Hero Neos,instead of Elemental Hero Neos Alius.
- This card does NOT combo well with Instant Neo Space. Instant Neo Space says that "When the equipped monster is removed from the field, you can Special Summon 1 "Elemental Hero Neos" from your hand, Deck, or Graveyard." This card says "Return 1 "Neos" Fusion Monster you control to the Fusion Deck. If all the Fusion Material Monsters listed on that Fusion Monster are in your Deck, you can Special Summon them." Notice the "cans"? Because two "cans" happen at the same time, Instant Neo Space will miss its timing.
