Got a bit stuck on the second gym leader, but after I passed that stage it went really good. The RNG is fine, the content is really great, has some replayability and you get rewarded for your time. I got so powerful at the end because i grinded (just because i wanted more cool pokemon, not because it was really needed) and I usually hate grinding.

Took me 2 night sessions and couple hours to have 40 lvl10 cards with some maxed out, about 6-8h.

Really enjoyed this, I wish it was official :)
