I've combined Ae's strategy with mine.

First round:
Conquista: Hfishy Ice Hydra with one more HP then the rest
Sam: Seppuku on the Ice Hydra with one more HP then the rest, then Animate dead on the one that just died
Faw/Bob/Fooruman: N.
Shuriken: SW, S.
Furious: Attack Ice Hydra
Araches/L33tz4n: E, Attack Ice Hydra
Animated Ice Hydra with more HP than the rest: Attack Ice Hydra

Second round:
Furious: Attack Ice Hydra.
Araches/Leetsan: Attack Ice Hydra.
Sam: Defend.
Grandma: Defend.
Shuriken: Defend.
Faw/Bob: Heal on Shuriken (she can be killed by a teleporting Solstice ).
Fooruman: Defend.

The formation of Grandma/Sam/Faw-Bob/Fooruman is quite strong, and we should hold it until all spells have run out.

I will also make appropriate arrangements for round 2, depending on how Radium moves his pesky hydras. Also,
