It seems like Bubblestrat doesn't work anymore. I defeated my 20+ CP Krabby with Bubble using my 17 CP Diglett, and I only got 100 prestige points. I concluded that the new gym setup ended Bubblestrat and then transferred all of my level 1-3 Pokémon. If Bubblestrat still works, then I have really messed up by getting rid of all of those Pokémon.
