Simple fix. Allow only 1 or 2 prankster pokemon per team. This is the best solution for all.
I don't get why people who are anti swagger prankster ban keep suggesting this, since it literally does not address people's concerns with this at all, and imposes an unnecessary team building restriction that does not address the problem. By insinuating the number of prankster swagger users that should be allowed on a team be limited, you are essentially agreeing that it is an uncompetitive strategy. However there is nothing inherently uncompetitive about using Klefki, Sableye, Thundurus, and Tornadus on the same team, so your ban eliminates legitimate competitive strategies as well as failing to address the uncompetitiveness that goes in hand with prankster swagger.

No one wants to remove all elements of chance from the game of pokemon, no one has even argued that. People have a problem with people using a "strategy" of introducing as much luck into the game as possible, a series of coin flips, in order to beat the other player. In games without prankster swagger I would say the player that exhibits more skill wins ~ 75% of the time, in a game with prankster swagger where it is almost completely up to chance, this is not acceptable in a competitive game. Prankster Swagger removes a large portion of the element of decision making that differentiates competitive pokemon from games of pure chance like roulette and candy land. Neither of those games are competitive, and neither is prankster swagger, so a competitive pokemon university should attempt to remove this "strategy" from the meta game.
