do it in 5 turns now. if your luckier with rush hitting the dark hunter you can do the around 10000 damage remaining. you also deal around 3000 damage with survivalist before turn 6 if you use multihit instead of Apollon and getting your dark hunter hit 4-3 more times might kill it so use an adamas or moss coat for the extra def and elemental res due to the weird damage calculations. I don't know if this is enough but you do only need to do around 7000 extra damage before turn 6 to win
