My greatest cheese yet!

Not really a cheese, so much as playing to the only strength I had, which was mobility and Tyrion's badass melee ability. Circled and hid in the forests for the first half of the battle, picking off units of opportunity. Once Tyrion and Caradryan were surrounded, I spammed Sunfang and pitted my wizard against theirs. Once theirs fled, the morale tanks (as is the way with rats) and the rest is history. Very hard mode; computer predicted decisive defeat.

TL;DR Don't trust autoresolve
