Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Mew already has way too much speed, also dunno if you noticed, Chansey and Azu speed tied, and i won all of them(there was one switch that azu did before chansey switched, suggesting the tie)
What do you think about Protect>Magic Coat on Mola?
It'll leave more open to Taunt+SR Terrakion and Ttar(Ice Beam+Fire Blast) and Taunt+SR MAero but will help against those wallbreakers, ease some predctions and maybe even save 1~2 mons when against toxied Garde/Hera
Derp I forgot to add it really depends but I like it on my team... It helps with certain stallbreakers and relieves pressure from skarm but protect could be useful for toxic stalling annoying stuff like you said. Really depends what you want I would add leftovers if you run protect as the added recovery is nice.
