One for all and all for one 4

Perhaps one of my most painful losses of all time. Playing almost perfectly, the game was turning in my favor, but... the opponent showed up right on time. Right when you least expect him... on 117... the armies are comparable, but mine are on a scout hero, while Gunnar was waiting at home for the next day, was taking Dwarf Cottages, was about to clear 2 Dragon Fly Hives and would have come visiting himself... but the opponent killed the scout hero, who didn't have a single battle magic spell—absolutely any spell, Haste, Slow, Bless, even a damn something would have simply won the fight. The opponent was left with 2 Air Elementals and a Roc. 121 - dilemma. No money, no troops. Barely, by swapping all resources and the treasure chest for 2000 gold, I bought whatever troops I could from the starting week + a hero, took a decent-enough stack of 20 Dwarf Cottages, I realize I need to quickly clear my 2 Dragon Fly Hives because near one of them stands a Müllich who will get a reinforcement delivery. I attack the guard with 3 Horses, 13 Grand Elves, 50 Centaurs, 5 Dwarves, and 4 Wood Elves—a horde of Fire Elementals. The calculator showed 60, but there turned out to be 70, and of course with the most annoying Growth spell... I killed 60, 10 remained...
Thanks for game, really well played, one chance for win - and its lucky coin!
