Hi guys.
Haven’t play the game since 2016 (Whispers of the Old Gods). Always was playing exclusively arena. Resently deside to return to the game to try out arena once again. Is there a complete arena rules set that I can found anywhere? What I mean by that is: what cards have increased chance to appear, what card are banned, maybe there are set amount of spells you can get in the draft, etc.
Sorry for my English and thank toy very muck 
There’s some statistics in HSReplay. But not sure if that’s what you want.
You kinda just learn by playing. Class cards can be strong. But for arena even for past people who used to go 12W it’s a rough patch.
Ever since the chinese servers closed, bleed in of people running bots to superdraft (get 2-4x copies of the best cards for streaming) has become a thing.
Some cards are so powerful in arena like the titans. That if you can’t answer them in arena, you just lose. Like eternal 2x 3/4 taunts for the rest of the game with a 10 health card that summons a pair of 12/12s next turn who ALSO cleared the board when played. (Arena sargeras.)
It’s just a bad time to try to go infinite in arena. Average decks that used to go 5-7 wins on pilot skill get a person playing supercards 2-3 win brackets earlier now.
