I also play GU, it's great and has potential but for now, it's not that beneficial. it uses the ethereum network so the gas fee cut is very huge. I played for a month so far I've got so many packs freely from just playing and leveling up (30 probably more), now I am selling at least 12 cards, most of the cards I use myself (4 cards sold, $0.25 each), 1.7 GODS (4 dollars more/less), and only finished last 2 weeks of weekly challenge (approximately $4 value per week)
