Who do you think will win?

You don't even need to summon Elementals. I just cloned Medusas and Eyes and shot down the skeletons under the Berserker. Easy win with no losses!

In this battle, the main thing is to eliminate all troops except the stack of skeletons in one round. And then, how you kill the berserked skeletons is up to each player's imagination, because it's not at all difficult.
