Numerounius ["IDGAF"]

variation sourced from original IDGAF = horus into vanity's into ryzeals into board wipe into imagination

NB: replace numbers protection with new and improved "XYZ Unbreakable Barrier" for the better Astraltopia search card

EDIT: [3/9/25] UPDATED DECK TO HAVE MORE PROTECTION FOR NUMEROUNIUS, TYPICALLY IN THE FORM OF PROTECTION SPELL AND TRAP CARDS. IF NO PROTECTION IS ACTIVE, IT IS A 0 ATK / 0 DEF MONSTER WHEN SUMMONED REGULARLY (MEANING IT CAN BE EASILY ATTACKED AND SIMPLY DESTROYED WITHOUT ACTIVATION).

likely one of my last theorycrafting decks to make, but this deck has been a blast and still is a blast to play imo. it feels like a culmination of all my posted, public decks (specifically) and i love that

there are a lot of processes behind it that can go either way depending on your hand— usually you would go horus or ryzeals or both (both is best) and vanity's still as a main focus

ranking up to C1000 goes from gimmick puppet fantasix (while using both effect card and xyz summoning mechanics listed in card text) all the way up to number 84: pain gainer from the other xyz rank cards. as long as you aren't negated or interrupted in any way shape or form, this is a guaranteed way to climb to C1000 Numerounius.

from C1000 Numerounius, if you drew ryzeals (bonfire AND seventh tachyon helps search, seventh ascension searches for tachyon) or level 4 supports , you can consistently pressure opponent with both C1000 Numerounius and Dark Matter Demolition or Ryzeal Detonator. Dark Matter Demolition comes from Utopia Double into Dragonar into number card of choice (between 1 to 100). Dark Matter Demolition's "Cannot be destroyed by battle or card effects" works in synergy with Numerounius, where Numerounius continues to destroy and can ressurect your opponent's monsters, while Dark Matter Demolition can continue to attack due to it being unaffected by Numerounius' destruction effect. likewise, ryzeal detonator can also avoid destruction and pressure opponent alongside Numerounius (albeit costing material in the process), whereby: "If an Xyz Monster(s) you control would be destroyed by battle or card effect, you can detach 1 material from this card instead." horus monsters with king sarc up also avoid destruction due to the first line: "Horus" monsters you control cannot be destroyed by card effects that do not target them."
