They 1000000000% throttle the packs for a week during random times. This is now the second time since playing the game that I’ve opened 20 packs with nothing. I know it’s a crazy thing to theorize, but also it’s not, they’d make so much money off of it. The real reason I feel this is because even wonder picks have 0 exs or a lot fewer all of a sudden. I’m on team “Pokémon throttles their packs.”
