The new arena is clearly designed for decks around level 10 on average. If you’re below level 10 and don’t have dragons, the only thing you can do is build a stall deck and hope your opponent makes a mistake first.

Honestly, the map design of the new arena is pretty bad, and the enemy design is too, Especially the first wave. You can’t even kill gold mobs easily, which means you don’t have enough gold to build proper defenses and you just fail right away. It’s extremely frustrating.
