I usually take the Pao-Kai, the lightning from their mouth does its job, hitting several enemies at once, but the poison affects everyone differently.

The best are the Dark Wyverns. Imagine, Pao-Kais are standing there, and orcs are around them, and then they are attacked. They strike randomly. And they die along with the enemy, and your own warriors die too. It's not very pleasant.:) :smile16:

Once, I shamefully lost to the computer in a triple duel. (Final: Lethos-Shak'Karukat). I had Night Stalkers with vampirism left, and he had Pao-Kais, which ate all the corpses that littered the field after three pairs of heroes. In the end, the vampirism ran out, but there were still corpses...

I take them depending on the situation, mostly Dark Wyverns, poison and regeneration do their job.
