What kind of magic do you like?

I also played this battle; I don't know how much mana they had, but it doesn't really matter, and who goes first isn't that important either. The druid's first move is to cast antimagic on himself, and for the mage, I think Mirror Image would be the best. Then, the druid summons mantises (level 19, 3 mantises). The mage has two options: either hypnotize the mantises or cast Phantom. In the first case, the druid casts antimagic on his third turn, and the problem is solved. In the second case, the phantom is less effective (the number is the same, but the druid's mantises destroy one of the mage's phantoms with the first attack). All the druid's remaining turns involve casting Swarm on the mage. If no one gets a spirit, the druid easily defeats the mage (the druid "holds" the mage, the mantises first deal with the illusion and then with the mage). If someone gets a spirit, that person wins, but that's not equal conditions.
