If you want to know the best clan, it's really subjective, but the chaos desert clan is awesome. IF you aren't dead quickly, the combination of burning, 10 extra fireballs, along with damage multiplying lets you land hits of up to 170 damage from a normal shot.
This was a great game, yes it needs a better tutorial, but if you read the beginning instructions you can find out in around 15 seconds. You should also make a mode where you are untimed, or something easier, so that you can play on the farm all you want.
