Ive been playing exlusively Sunstall on my alt Pleasure for about 2 month now and ive peaked #1 (i think ~2120 max rating) several times (and beaten players like panamaxis and Taylor and idk) and am like almost always in the Top100 (depending if i decayed or not).
Used an old BW1 Sunstallteam: Ninetales, Dugtrio, Xatu, Volcarona, Slowbro, Chansey. (Yup i ran Xatu+Dugtrio way before Lavos made it popular even back in late 2011.)
Sadly this type of team isnt working as well anymore since people started to run SR on Terrakion/Landorus. Lets just say winning vs. SashTerrakion-Offense and Torn-T+Thund-T-Rain is quite hard. I think i win most of these matchups just due to skill and dumb matchmaking (1500 or lower ppl vs me).
Just did 1 match to fight of the decay and am now at spot #25. GG!
But yeah will prolly make a new alt with another team since this one probably wont be recognized because ive been using it for the last 2 month.
