Who says ball of lightning isn't the best dragon ability?

I'm suspicious that you can actually do even better than 134k... if you have sufficient patience. Resurrect 3, Mana Spring 3, Call of Nature 1, archdemons, and 1 gorguana... against skeleton archers and ghosts. Let the gorguana die; use the high initiative and speed of archdemons to keep them out of range of the ghosts. Whittle the skeleton archers down to just a few units, then use mana spring on your archdemons to restore mana indefinitely. Call of Nature to give the enemy ghosts a nice target to Soul Drain. You should be able to grow the enemy ghost stack to an arbitrarily large size. Then you kill off the enemy skeleton archers, resurrect your gorguana, use mark of blood + peacefulness, and follow up with Ball of Lightning.

I've never used ghosts, so I'm not certain that they drain summoned animals; that's the only point I can see where this could go wrong.
