Joined 5 public CM rooms. Won 2, placed 3 with my proof of concept Golshi (I had 1180 speed instead of 1200). Every room has at least 1 debuffer (Nature, Tachyon second, saw one guy with Grass), and all of them had something to target End Closers and some variety of the other styles but not so much Late (so that's a blind spot... unless someone is autistic enough to hit all 4 styles). Most popular aces are Oguri, Golshi, and Suzuka. Sometimes people bring both Oguri and Golshi or Golshi and Suzuka. Just have to adjust my ace a little bit and I should be good.
