I didn't play very well, made quite a few blunders, but got lucky and won.
At the native respawn, the external dwellings were for hydras, behemoths, and wyverns; I only colored the wyverns.
At the second Griffin Conservatory it was a minimum build; I painted the behemoth external dwelling, but was afraid of the hydras, and besides I already had other plans (guarding the upgraded Ifrits), so I took the hive at home for 8 wyverns.
Money was tight; I took Rampart as a secondary.
In the end, I went with Gunnar to the revealed Griffin Conservatory in the snow, and luckily I saw Pyre there with a speed-stack of 11 upgraded Ifrits, and nearby a scout hero with the other part of the army. I bought everything to the max, the chain was fine, and I attacked. Roman decided not to continue.
Thank you Roman for the game !!!!!!!!!
