I'm sceptic bro. if they could hack gems they'd have 9999999999999999 and not just 900k
with a little patience you can get the same amount with this mod
when i couldn't use my main account with the mod, i created a new account and used the old mod. today i casually grinded for gems in the tablet using an auto clicker. I'm sitting on 250k gems at the moment, i haven't used any. so 900k is totally doable
I've seen the drama in their discord. i see a lot of users complaining because now there's a limit of daily battles so they can't use clickers/bots to grind for perks taking advantage of the paid pass as far as i understand
now playing 2 accounts, main account with no gems but a decent deck for my level playing legit on Playstore version of the game, and secondary account 3% might accumulating gems lol
