Alright, for this i need 1 sacrifisal gnome + an assload of AoE deepeess.
What the plan is:
*We run into the busiest Horde town and while sticking together we have a party. Hopefully loads of hordes come to us and murder us to pieces.
*the sacrifisal gnome MAY NOT die, he/she will be using
Flask of Petrification before he/she dies, making him/her untouchable for one minute.
*the assload of AoE deepeess will run back to their corpes asap, NOT ressurecting yet.
* when the minute of god-like-ness of the gnome is almost gone we should have drawn the attention of a big load of hordies, trying to smash the gnome.
*Then we ressurect, all together, and do our most awesome, painfull and reckless AoE dps we can, we should be able to kill atleast 10 hordies, if not more

sounds cool!
for an example, some hordies did it in IF:
