Put me in the minority, but I am actually not that excited about the Tsareena GX's GX attack. Notice the energy cost. It is possible to get [G][G][C] on Tsareena T1 or T2, but ultimately it needs to be in a deck with Vileplume to really make much sense. Basically, the idea would be to get a Tsareena + Plume up T1 (similar to the goal with Deciduplume), but instead of techs doing damage, Tsareena is your tank and primary damage dealer. Basically, this looks like a very slow concept that is also extremely dependent on being able to stick a Haunter (which you won't want to use because FoGP is more important) or your opponent not being able to retreat out of a Glare which is far more likely. It looks clunky ATM. I took a look for other "opponent's active is now confused" pokemon abilities / trainers that perform the action and found none.
Long story short, without the ability to consistently apply confusion without also confusing Tsareena GX, I think this is a niche card that won't see much competitive play. That's a shame too because it would really only take one good confusion card for this to be a pretty scary card.
