As usual, they didn't manage to defeat me; I had 2 Knights with Subjugation and Gargoyles, which are fast. I positioned the Gargoyles to be hit by an Imp, so he wouldn't gain mana; his troops are very fast. I managed to win. Now I need to try and gather the trees.
Reinforcements finally arrived. After I defeated the Khan, reinforcements arrived, but only 1 of them made it through intact. In the end, https://c2n.me/48hA1A1, the reinforcements were quite pathetic. Well, I'll take one of the heroes and change him.
I won! Hooray!)
