In short, what I got was that I shouldn't restart. Not only were Moneer and 3 Necromancers among the first five heroes, but the 6th hero was Galtran, with an Air external dwelling nearby. Along the way, blockers were mostly non-shooters. On day 121, I had 140 Skeletons. Killed 2 computers: native Conflux + Rampart. Wyverns were stationed in the Fort. By day 125, Skeletons were already 348. Found 3 Dragon Utopias along the road from Rampart into the treasure zone — two turned out to be small and one large. On day 132, in the second Conflux, Wyverns were already stationed in the Citadel and I started taking on the Dragon Utopias. Final stats: 18-22-27-190, 400 Skeletons, 9 Wyverns, 21 Wyverns, 7 Psychos, 53 Storms, 11 Firebirds, Tome of Earth, and a mad Galtran at level 18-19 with Attack, Defense, Logistics, Wisdom, Earth, Air, and Necromancy. I rushed to make contact. Kyrre arrives with stats 15-27-17-108.
15 upgraded Unicorns, 25 Wyverns, 2 Angels, 86 Grands, 19 Pegasi, 164 ordinary Centaurs, and a single Pegasus.

I immediately cast Implosion on the Grands. In response, I get Slowed and rushed. In round 2, I take an Implosion on the Wyverns — I endure! I cast Mass Haste and charge in. In the next round, the opponent casts Implosion thanks to the 14 speed of the Pegasi into the Skeletons, immediately gets a Resurrection for the same number of Skeletons, and hits harder than me — clearly my skills were trained worse! In round 4, I immediately resurrect the Wyverns, cutting down almost all units except for 9 Wyverns. My losses: 11 Wyverns, 80 Skeletons, 5 Storms, and Firebirds. The opponent could have continued but didn't want to.
Thanks for the game.
