>>49852011As soon as you gain access to the Train station, you can travel to the Isle of Armor and start doing that part of the DLC. I think it's probably less than an hour of play to get to the train station. Then, I imagine it's probably less than an hour again of play once you're on the isle of armor before you gain access to the Cram-o.
I'd actually encourage doing it sooner rather than later. The difficulty is scaled based on your gym badge progression, I think. As opposed to Crown Tundra, which is intended to be done after completing the main game.
What
>>49852070 said is true though. The Cram-o-matic has horrendous odds for actually spitting out an apriball. You get a single apriball as a prize from 'ball guy' after defeating a gym in the story. Friend, Lure, Level, Heavy, Love, Moon, Dream. In that order. So it might be more efficient to just play the game and grab that if the one you want is fairly early on.
You won't really get a great chance to horde apriballs though, without injection or giveaways.
