I'm Scarlet, but I'll try ^_^

I'd do Shark Bomb over healing, just since it's 4 rounds and if you survive Exploding Hell you don't have much longer anyway :(

Same goes with: whip over heal, shark bomb again (compare the damage of those two?), Water Enhancement (Kyuubi can't be poisoned), and I'm not sure what Soul Absorption does but if it's damage causing go with that.

If you have another summon throw it in the third slot for more power. And change the summon based on your team choice.

And... um... since I suggested Water Enhancement maybe go with a water team, unless that just doesn't work for you? Otherwise, I'm not sure I can help until I know what the chase conditions->results are for your main's talents, sorry.
