• Note that this card's first effect can also affect your opponent's Xyz Monster too. If an Xyz Monster you control with 2 or more Xyz Materials battles another Xyz Monster with 2 or more Xyz Materials, then your opponent's monster, if it survived the battle, will not be destroyed by this card's effect.
  • Use Numbers Overlay Boost to recharge your spent Xyz Material and remain protected by Xyz Tribalrivals.
  • This card works greatly well with "Number 92: Heart-eartH Dragon":
    • While having 2 or more Xyz Materials, it will not be destroyed by card effects, so you will be able to keep on using its banishing effect. When it have 1 remaining Xyz Material, this card won't protect it anymore, which is good, once when destroyed as long as it have an Xyz Material attached to it, its self-Special Summonig effect will activate and it will return to the field with a huge ATK boost.
    • These cards also get along as "Tribalrivals" destroys the monsters "Number 92" battles, so when it attack a strong monster, it will not only deal a heavy damage, but also destroy the attacked monster.
  • This card works well with "Number 9: Dyson Sphere", as it can protect itself against attacks and this card against effect destruction.
  • When you Xyz Summon a monster, you won't have to worry about cards like "Bottomless Trap Hole" that would destroy it.
    • Even better, you can chain this card to the activation of a card like "Torrential Tribute" (when you summon a monster) and "Mirror Force" (When you attack), making your opponent waste resources.
  • You can also use cards with mass-destruction effects like "Dark Hole" or "Torrential Tribute" to destroy only your opponent's monsters.
  • When using this card with "Mermail Abysstrite", she can stay destruction-proof for a long period of time, drawing in Attacks with her effect and causing any monster that attacks her to be destroyed.
  • A monster summoned by using Rank-Up-Magic Astral Force a few times can amass a lot of materials and be a good candidate for this card.

Traditional Format

  • "Number 16: Shock Master" (while still having 3 Xyz Materials) can use his effect to protect this card against spells like "Mystical Space Typhoon", while being protected himself against destructing traps like "Mirror Force". You can use "Overlay Eater" to replenish his Xyz Materials, while taking them from your opponent's Xyz monsters, making them vulnerable.
