I’m currently playing some game in arena but I have the exact same feeling has playing at a tavern brawl that give you a random deck.
The only thing that give you victory is the luck to get one card that can just return the game and/or have no counter play at all…
Too much rng for arena, you can take all value trade you want, there is always one broken card that will ruin your game (or ruin the opponent one)
I mean, it’s supposed to be arena, not wild and even less tavern brawl.
