Archers didn't come with the heroes, but there was an external dwelling of pikemen along the way, so on the first day, pikemen decided the outcome :). I painted the necro village (nearby external market), external dwelling of archers, houses 1-6, without 5 in the citadel, Edric in the walking dead, already with expert Tactics.
On the second day, I break 2 dwarf dwellings (maximum and pre-minimum), a lot of gold, I upgrade griffins and crusaders, buy everything out, break into the necro village, buy a spell book, nearby Griffin Conservatory - I'm about to take it. I checked the enemy - a triple, I go in. I only had mana for 2 Slow spells, so they roughed me up a bit (minus crusaders, 15 Marksmen, and cavalry), but got 3 Angels and a Castle-Rampart castle with an external dragon dwelling and 2 clue scrolls glows nearby - I head there. I broke through 80 Air Elementals and 30 Psychic Elementals, managed to paint the external dwellings of dragons and unicorns by day 127.
On the third day, I rebuild the Rampart, paint 2 more villages, break hives (4+4+6), another maximum dwarf dwelling, buy a Cuirass +2 and Shield +6 from the Black Market, scout with the View - the enemy is very close - behind an unbreakable guard. On day 137, I break through with all my army, capture the barbarian village, kill the enemy. Dragon appeared with 1 Fly on my secondary hero on swamp terrain, ran around a bit and broke back home. I have expert Air Scouting - the enemy's movement is like on slow.
On day 141, I buy 4 dragons, unicorns, Marksmen, and cavalry, move toward the blue capital. We traded a few heroes, I already have 8 castles against the enemy's 2. Dragon attacks:
Thanks to Mass Haste and Ice Arrow on day 170, I managed to easily win, preserving more than half of the army.
Thanks for the game!
