Is it possible to defeat 1000 Archangels with just one Imp?

Message from Denminator
Since Archangels are level 7 units, they have high power. You can cast the "Berserk" spell, and they will kill each other. Then, use "Explosion" on the remaining ones, and hide the demons behind obstacles.

Dear Denminator, please try to understand the situation before commenting. There is a stack of 1000 Archangels hidden in a castle. The hero attacks, slows down, and blinds the Archangels. After that, he summons legions of elementals and systematically eliminates the Archangels, securing the victory with an explosion. If a demon dies, it can be resurrected by the end of the battle.
