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.
The team looks pretty good I'm going to test it out and get back to you!
Edit: Recommend focus blast over giga drain or leaf storm for sceptile to hit steel types with levitate or balloon etc. And also i think equake to HP rock for talonflame switchins.
Also after testing one battle this...
I tested this team it's pretty great but I vsed one of Rumplestiltskin's alts and he keeps beating me with Mega Altaria confide/iron defense/roost/hyper voice spam. I tried all 3 pokemon but I can't OHKO it.
Edit: I swapped out trick on Meloetta for Dazzling Gleam that way I can 2HKO his...
Also I'd swap Analytic from Starmie to Natural Cure since it's generally a fast pokemon. Also Frustration over Return and min happiness for Lopunny incase of the random Dittos.
Team looks solid except I would run ice punch over power-up punch on lopunny to OHKO dragonite after fake out, etc. Also would you run this over your Deadly Sins team or is that one still better?
