And I really want Zygarde to have the serpent theme going here. Rayquaza is most certainly my favorite here, but would it actually be okay if it were to be without Mega?

(its just a glass cannon after all)
Also after a few tests
Contary is not that op, It just allows spamming of things like leaf storm close combat and....

okay why is Contary not op? - Hold up just awnser my own question, SERPERIOR HAS SHITTY COVERAGE... 

But for all intensive purposes others can also exploit it so... Yea its allowed
