Though, Magic Bouncers are always a counter to prankster users. I am worried if Prankster is let in that we'd develop an ability triangle similar to the BH lead triangle of Mold Breaker, Magic Bounce, and Prankster. While I do argue Prankster Breloom is broken, I don't think it's that brtoken on anything else besides our loveable pink blobs. Prankster Softboilds, Wishes, Toxics, T-Waves, Heal Bells, or whatever you run on them now get absolute priority. Toxic+Softboild stall is pretty much going to be more annoying then Sabe's RecoverWisp Stall. Not to mention CHansey can actually take a physical hit. Forretress and Ferrothorn would also love prankster, due to priority hazards, and Leech Seed in Ferrothorn's case (It arguable would now be a better SubSeeder than Whimsy). Those who are just a little too ballsy could also attempt Prankster PerishTrap. Like I'm saying, Prankster gives a lot of walls more walling abilities, but it also easily balances out offensive behemoths like Poison Heal Regigigas.
Also we all know how CroCune's annoying to deal with, right? Well now imagine CroCrune with Marvel Scale.
