Tittle pretty much. I used to bot in 2014 and stopped cause of ban wave, dropped the game for a while. I have been playing again lately but there are just so many new cards I wanna catch up with... But I am worried of getting banned. How safe do you guys think it would be to use this right now and how can I make this safer?

Easier yes, but not possible for new players to get all the cards within half a year unless you Shop some packs. The hardest ones to collect are ofc Legendaries, these takes ages to get one but with alittle luck from packs and so on then you might be able to collect half of the ones which are out in 6 months time.

As for being reported, its alot safer to play in Casual than Ranked for sure since ppl care less if they win or lose to a bot there, where else I've gotten quite a few Friend request in Ranked, but not that many.
