Would this doubles uu strategy work?

Mew @ can’t decide on itemSynchronize252 HP/4 SpA/252 SpeTimid-Transform-Psychic-Aura Sphere-Roost

Shuckle @ can’t decide on itemContrary4 HP/252 Def/252/SpDBold-Toxic-Infestation- Shell Smash-Rest

Because Transform copies all stats besides HP, Mew transforming into Shuckle would become a Pokemon with ridiculous HP and both defenses, with THREE stats maxed. Toxic causes foes to take an increasing amount of damage each turn, and Infestation prevents those poisoned Pokemon from switching out. Shell Smash, with Contrary involved, would increase both defenses and protect it from setup. Rest heals all HP, Toxic, and forces the opponent to attack for 2 turns, wasting PP, while Shuckle does not. It seems to me like the ultimate stall.By the way, should I give them Leftovers or Leppa Berries?

To be frank: no.

While in theory it might seem like a solid strategy, like the comments section has stated, there are too many counters to this team. Substitute anything. Thundurus' Prankster Taunt. Double targeting. Opposing setup that can power through Contrary Shell Smash. (Mega Salamence can boost up and proceed to KO with some double-targeting.) Unaware Clefable. Perish Trapper Mega Gengar (if VGC.) The list goes on and on, and honestly, the hassle and amount of setup isn’t worth it.
