"only XL-4"

We tried all the restarts and then just played for luck. The starting army is very weak, only 3 air units, money is low, but there are two roads - one to a village and a one-way path, the second to a portal guarded by 6k archers, and three necros entered.
On the first, I placed the psychos; by scouting, I saw that the opponent had only one road, and judging by the fact that he didn't take a second town in the first week, I guessed it led to a one-way path.
On the second, I level up the necros, expanding own necros in two directions, took a comp, placed birds.
On the third, I take two more comps, build Mage Guild, find boots in a dungeon near the КВ road; the opponent's stats are twice as high, but he still has only one Castle.
On the 4th week, I start taking Dragon Utopia, get Town Portal in Mage Guild, and from three Dragon Utopia I get almost everything I need.
On the fifth week, the opponent starts seizing castles and killing supports. Having lost almost all castles and all supports on the surface, I was already on the verge of surrendering, but in the end, with 3900 moves, I reach the opponent's main almost on the last step and attack Dessa with shackles.
Thanks for the game
