Why not run M-Rayquaza? Why not use a Geomancy Xenreas set? Why not put a Z-Move on Arceus?

---

very wrong, look, you wanna use uber the last thing you wanna go is ruine their feature,
Rayquaza does need mega to make it even better, why water Z? weakness to ice type why not counter it with fire type move?
Xenreas' signature is Geomancy and it's not for no reason,

... and you don't have any move to raise your Def or Attack. too fragile
