Counter-heroes in duel mode (3.1).

Razazak vs. Ossir=)
What should Razazak do? )))) (Ossir's setup is standard: archers and druids in the corner on the back row, with nymphs on the side, protected in front by centaurs and brambles). I had no ideas at all; I just placed a cloud over the group, teleported dark golems to the nymphs... and got frustrated=))
