Tera Pokemon are immune to type changes caused by stuff like protean or soak, right? So if a Pokemon Terastallizes and then uses transform (or activates imposter), does it keep its type or transform into the target's type?
Pressure works only when the move is targeting the Pokemon with pressure, so it doesn't work on self-targeting moves (except imprison and snatch).
Also this thread is for the Smogon dex. Showdown! bugs should be reported here...
