Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
There are still some bugs on SW/SH Doubles:
-Weezing's Neutralizing Gas doesn't work while switched in (It have to activate)
-Pollen Puff,Heal Pulse, Life Dew still have issues with healing on Dynamax (they count Dynamax hps and not base form hps)
