Which is the best combination of cards to burst Zaiba?

3x Froster Lord?
3x Chappa
1x Froster 2x Hidra?

I imagine that the combination of froster plus the quick hit of zaibas would apply the frost bite a good amount of times. But I didn’t have tested it yet, there is someone to give me an idea of its effect in practice? 3x froster is too much? 1 is to less? Should I forgive it tottaly and go just for chappa?

(another question, frostbite works on boss?)
