>>20773591Then it would probably be banned to ubers, or even from ubers. If it were running Wonder Guard then nothing but fighting-type moves, status, and weather could touch it. Without 1 hp like shedinja, weather does jack shit. And with Mew's movepool, it has access to Recover, Heal Bell, Magic Coat, Taunt, and lots of other moves to wall any opponent without fighting-type moves.
It could also run some broken-ass baton pass sets. Speed Boost+Nasty Plot/Swords Dance+Baton Pass in two turns. All it'd have to do is use Protect, then nasty plot/SD using its sash, then Protect again, and boom, instant +3 spd and +2 Sp Atk/Atk for anything. Or it could run a BP set, with Wonder Guard, so that if the opponent doesn't lead with the right mon, guess what? It just got a free turn of setup, and the opponent may be totally fucked.
And that's not including the possiblity of it running Magic Bounce to fuck over potential phazers, or just Taunting after a speed boost or two.
