Things like this make the tier a bit more luck based -Getting Weather Abusers that don't match with your weather inducer (Ie:kyogre w/ excadrill, Kingdra with Groudon) -Near useless pokemons such as Spikes Smeargle in Ubers (Smashpass would be more acceptable, but stuff like this is so gimmicky it shouldn't be included)
Gbatemper: I assume you're saying you want this removed. Remember that BF 6v6 and BF use the same sets, so what may not work in BF may work extraordinarily well in BF 6v6.
If you feel as though the tier can be improved, comment on sets that need deleting in the channel #BF Review Type /commands battlefactory when you're in the channel
