Hey all, i started playing this game a few months back but left as i could not find any decent guide and early game tips. I just came back because i kinda like the game overall & want to give it another try.
Basically, i am looking for help on the following but i would also like to know if there is a discord community which i can join. The link which is available in the forums here does not work - invalid invite error.
- Early deck building advice - which cards to upgrade and use in deck?
- Strats of deck building for campaign
- Event specific deck building guide
- Game Shop & Event shop buying guide - what to buy & what to save for?
Please help out if you can so i can enjoy the game more 
Thanks!
