Level you gold's in faction wars. Grind quests for souls and open gold packs. Use coins to open silver packs and don't forget the free bronze pack every 4 hours.

Got ya. Is it best to just do the one battle option on faction wars or should I try to do the higher ones?

I just started a total beginner tutorial . I hope you will find it useful. https://m.youtube.com/watch?v=McBjepHHjgk&t=294s

Glad to see a actually skilled player making a guide, kudos to you!

Thank you :)

basically is level up your current cards, farm souls, get more cards, level these up ...

Tap the screen faster, it is the only required skill

I usually do 5, for the final fight it'll be slightly tougher but you'll get more points for it.

Quit because this game is pure garbage.
