You can then feed said Treasure into Mr

PGR Premium Gold Rare Nibiru, the Primal Being X LIGHT Level 11 [ RockEffect ] ATK 3000 DEF 600 During the Main Phase, if your opponent Normal or Special Summoned 5 or more monsters this turn (Quick Effect): You can Tribute as many face-up monsters on the field as possible, and if you do, Special Summon this card from your hand, then Special Summon 1 "Primal Being Token" (Rock/LIGHT/Level 11/ATK ?/DEF ?) to your opponent's field (this Token's ATK/DEF become the combined original ATK/DEF of the Tributed monsters)

You can then pay 2 and sacrifice it to wipe the board of everything at that cost

There can also be some shenanigans regarding making absurd amounts of tokens if you have a strong enough board but, again, thats just how the game works
