"ALLRANDOM"

Wow... And what does speed affect?... Why not take 6 flies then? And does the stack order matter?

It seems that faster stacks attack the griffins themselves and thus keep them at the edges of the battlefield. Simple gnolls get beaten up by the griffins and end up in the center.

There were only 4 flies available, not 6. I put the hydras in the first stack, the griffin gnolls in the 3rd and 6th, and the flies in the rest.
