How do you beat Super Boss fights with no losses?

I just beat the Frog on turn 1. LOL!!!! My stone skinned Knights hit him and he retaliated for 43 damage. My pallies critical hit him and he was dead.

Spider was just as hilarious. He summoned his spiders, the Giants stomped and there were like 4 still alive. Turn 2, the boss was dead, but because of the 4 spiders still alive I was able to resurrect my 3 fallen Knights.
