[RATE MY TEAM] First attempt at trying to come up with a team

[LonerBird]

My setup for BSS was the same as my battle tree team and ive had pretty good success with it.

Mimikyu
type- fairy, ghost
ability- disguise
nature- jolly
item- life orb
evs- 252 spe, 252 atk, 4 hp
moveset- swords dance, play rough, shadow sneak, leech life

Greninja
type- wter, dark (changes with protean though)
ability-protean
nature- timid
item- focus sash/ expert belt
evs- 252 spe, 252 sp.atk, 4 hp
moveset- ice beam, grass knot, surf, hidden power (fire)

Charizard
type- fire, flying ( mega x- fire, dragon)
ability- blaze (changes to tough claws in mega x form)
nature- jolly
item- charizardite x
evs- 252 spe, 252 atk, 4hp
moveset- dragon dance, fire punch, thunder punch, focus punch

Hope this helps. Mimkyu is very underrated, with the right setup, i OHKO legendarys :D

also, wouldnt recommend sandslash unless its for doubles, sandslash needs hidden ability slush rush and ninetails to be of any use. would get ko'ed by any fast fire types otherwise.

whiscash is pretty great, since it knows both earthquake and muddy water. both moves would get stab.

talonflame- traded a bewear for it and havent seen it since, i think its in the back of my boxes. not sure if its good since i havent used it.

mimikyu- best pokemon out there.

have fun!!!!
