252+ Atk Tough Claws Mega Charizard X Flare Blitz vs. 252 HP / 104+ Def Mew: 235-277 (58.1 - 68.5%) -- guaranteed 2HKO after Leftovers recovery - Can also ddance/sd, better stabs
252 Atk Tough Claws Mega Metagross Meteor Mash vs. 252 HP / 104+ Def Mew: 175-207 (43.3 - 51.2%) -- guaranteed 3HKO after Leftovers recovery - worse stab, but better speed tier. yet still nearly as powerful, would definitely overpower it if adamant but nobody runs adamant megagross
252+ Atk Refrigerate Mega Glalie Return vs. 252 HP / 104+ Def Mew: 186-219 (46 - 54.2%) -- 4.7% chance to 2HKO after Leftovers recovery - wasn't sure if glalie usually goes jolly or adamant, but here's adamant for the benefit of the doubt
There's also diancie, megagarde, charizard-y, but they're primarily special attackers. Arguably glalie can hide if it's physical or special until it comes out, but charizard does that better. Also ice is a garbage typing. That is why mega glalie is not ou.
