Ok...I guess we can wait for agreement, but here are Ae's/my moves which I call Operation Sickle-Cut, after the infamous German blietzkrieg campaign in France. Actually, I am not sure if what was concocted will work, since we will be casting more than one spell (but Sam does have Unload mana, so it should work...right?)

Grandma: Hellfishy Ice Hydra with one more HP than the rest.
Sam: Seppuku on the Ice Hydra with one more HP than the rest, then Animate dead on the one that just died.
Faw/Bob/Fooruman: All move 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.
