jumbo card sleeves L Oversized (50) XXL Cards – Friki Monkey

If this card is Special Summoned: You can Special Summon 1 "Super Quantal Mech Beast" Xyz Monster from your Extra Deck using this card you control as material (this is treated as an Xyz Summon), and if you do, attach 1 "Super Quant" monster from your GY to it

The other possibility is playing Invasion of Regatha in a dedicated burn deck since the backside seems pretty powerful with Play with Fire, Lightning Strike, and friends as a weird twist on Torbran, Thane of Red Fell, although I'm not sure a burn deck wants to use multiple burn spells or attacks to remove the five defense counters to defeat the battle

With her, you can recycle your Ritual Spells and give your monsters a significant ATK boost
