Which level 2 creature is the best?

I created two completely identical heroes and played with both, meaning the tactics were the same, and I couldn't defeat the dwarves, and I didn't attack with archangels right away. How did you manage to win?:confused:

What's so hard to understand here?
We take down the golden dragons with archangels, the death knights attack the archers, the archers attack the death knights again, and the dwarves just move forward.:D
Then the actions repeat. After the archangel takes down the death knights (3 archangels remain), we resurrect the archers and can attack the dwarves with arrows for one turn until they reach us. Then the archangel and archer together easily defeat the dwarves. In the end, there are 2 archangels and about 30 archers...
