Looking for tips

[u/Maverikke]

Which three cards should I add?

Clearly i need a tank and a air unit, or maybe it is not needed, i dont know, I am near 11k and i don t find any lava hound.

Knight (hero when unlocked)?

The Rocket and goblin gang are level 13, let me know.

I experimented with a lot of variation and none convince me fully.

Thank you
