>>56883651If it's Booster Speed CM/SD, pack priority or something fat to get it off the revenge kill.
If it's Band/Specs, play around the switch but be careful of Trick.
If it's running some bullshit like Encore/Destiny Bond/Electric Terrain, pray your team has something that answers one or the other sets above. Glowking can eat Knock Off from the mixed set and OHKO with Sludge Bomb, but it dies to the physical set knock off. Conversely, Skarm/Corv eat the physical set alive, but get fried by Thunderbolt on the special set. Either overwhelm it with offensive pressure and double switching, or stonewall the boosting sets with unaware/phazing. If it gets forced out after Booster has been consumed, it's hard to do anything on the second time it gets in.
