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

I think this system would work:
1. Archangels are controlled by the computer.
2. The Imp somehow moves earlier.
3. Cursed Armor (slows, causes misfortune...).
4. A huge mana reserve.
Then, perform these actions:
1. Hypnotize.
2. Summon elementals.
3. Hide the Imp.
4. Attack them with an explosion or chain lightning (if there are many groups of Archangels).
BUT YOU NEED A HUGE MANA RESERVE.
Although, there's another option: if you have the Armageddon's Blade and the Archangels are divided into seven groups, summon elementals and Armageddons.
