Number Φ (Phi) : Perfect Xyz is a reference to the golden ratio, using the 2 consecutive numbers in the Fibonacci sequence as material and has a stat line referencing the golden ratio (1.618...)

Being made using the golden ratio makes it mathematically the perfect number monster, capable of xyz summoning using monsters on either side of the field, typically making more copies of itself with it's lenient materials, or another powerful xyz monster that was set-up by Perfect Xyz's level modulation effect.

(deleted old post, small errata changing the quick xyz from generic to "Number" Xyz monsters due to an overpowered interation with Dhampir Vampire Sheridan, thank you u/Tall-Bag-9317)

Wanted to make a circular for the Chimera Deck which gives the deck extension through negating it's crucial normal summon as well expanding it's play style by incentivizing playing non-archetypal illusion cards that I wish saw more play like the original Jongleur-Ghoul Illusionist and Vouiburial, the Dragon Undertaker. It could also add potential for more end board interactions like Heretical Phobos Covos and the Primite engine. At some point when making this card it had a fusion lock but considering it isn't a 1 card starter, I think it balances itself out in the modern era of yugioh.
