I finally made time to create a post, so here it is.

Round 1 vs MinasMorgul, SOD 6lm10a
Map looked great, I had a lot of money initially and Thant arrived in tavern, got expert necro fast. Then my only road ended in one-way exit (as red player), but fortunately it wasn't so bad because further offroad I found continuation of road. On 117 found boots, and on 121 killed fortress AI so I had some more army. Took some hives on week 2 and built MG, got TP on first try and Thant had perfect development, so no complaints there. Even got Galthran mid week 2, so I developed him for the late game. After this, my luck quickly fell down as my 2 topes were both mini and got +2all only. Then didn't get DD or Fly from 5 spells in tower. Towards late week 3 I didn't have good stats or DD, but fortunately opponent's situation was not great either and he conceded.

Round 2 vs Redwhait, SOD Mini-Nostalgia
I bought a pretty expensive flux, and we both used all restarts. Final map was nothing great, I got luna but basically no objects to take with her. Roads were quite bad, I had stables in my zone but still felt like an eternity to reach my AIs. My most decent hero was Broghild, but could not develop him fast. Since 121 I built/rebuilt MG every day, and got tp in 5 tries. I visited lava treasure but only found 3 hives, 1 cons and +4all. Scouted some topes in underground treasure, and one in dungeon AI zone. Most of these were really bad, the only good tope gave blue hat and +5all, I'm pretty sure opponent had full control before me, and even started clearing my last treasure before I could get there. I developed many supports, and started taking towns, but then Dessa appeared with similar army and AOTD+red orb, and continued to sit in central stronghold for the remaining game. This didn't allow me to control the map because I had no chance to defeat AOTD, except if I can assemble it too. Turns out the skull helmet was quest, so this map gave me slim chances for winning. I killed 2 supports of opponent, but at the cost of my Monere because I forgot to exchange wings and had no movement left to TP home. Even with support hero advantage, I could not take over map control because there were 2 sanctuaries in center of map, and even though I controlled both initially, later I lost these out of necessity / timer mistake. I could imagine 2 ways to win: take map control somehow and farm demons, then eventually get stronger, or allow him to attack me on swamp, where my monarchs are speed 16 and I surrender. Obviously, the second choice required no shackles on Dessa. I didn't really have safe towns left so I camped in my fortress town, outside of garrison to avoid instantly being slowed by AOTD. I could not surrender because of shackles, but I got morale in first round on my big stack on monarchs, and this basically destroyed Dessa's similar sized monarch stack, because I had a bit more stats and expert offense + wyvern specialist hero. So even though my situation looked completely hopeless, this morale gave me win in the end. I could not believe it.

Round 3 vs HellLight, SOD Diamond
I still had 1x111 left, but decided to play because I saw flux AI close to me with trade post and easy hive. Plus there was an easy box in my zone, which gave me 40 gargoyles. This allowed me to take 2 big hives on the first week already, and got a lucky scroll with TP on it. At the end of first week I recruited Gunnar, and developed him on second week. Tempo was really great, could take big cons early week 2, then more objects and boxes, and after constructing lvl4 guild I could easily expand into many directions. Took first tope on 124 with +12 att and +12 def, on 126 mini tope with +6all. On 127 I built angels in castle AI's town, and with angel dwelling, 2 dungeon portals this resulted in more than 15 archangels. Game ended on 131-132 when I stumbled upon enemy scout with army and artifacts. I didn't have DD all game, but had everything else I needed.

Round 4 vs Jelen117, HOTA 6lm10a
I have no idea how imba red vs blue is in hota, from what I heard the roads are well balanced so I picked blue fortress. The roads turned out to be my only complaint initially, but I could not restart it because tempo was great with mini cons from first day. Then with split armies I cleared my swamp, and flux AI's zone. Had a lot of time consuming fights with just 2 wyverns and 4 serpent flies vs lvl1-2 units. Still, my timer was not bad despite the many fights, I bought earth magic for drakon so I can take big cons 121. It turned out to be 100 griffs, and my wisdom suffered because I wanted to max expert earth. I got a lucky first roll of TP+Res, but got DD on 6 tries I think. I developed Daremyth, Mirlanda, Dessa for supports, and took tope on 126, but got gold sack. Meanwhile I already saw huge spell power on opponent, which meant I am dead in a potential final battle. I found another tope in swamp supertreasury, my reward was dragon scale armor and fire book (for my 4 spellpower ). So I was still marginally weaker because of stats, and was sure that I am dead once I saw full control on opponent. Somehow he didn't catch me, and I sent Daremyth off to kill cove AI on the far left side of the map. This journey took 2 days, but turned out to be my winning move because from that cove town I reached opponent's castle, and killed Miriam there with boots+gloves. Soon after Jelen gave up, even though he still had 2 good supports and big stats, so I was surprised when I saw the playback. But in the end, I miraculously won.

I didn't plan to win this tournament, because to be honest, there are many players that could beat me with similar maps. The competition is more fierce than it ever was. I needed some luck and opponents mistakes to win. I think the homm3 "meta" needs a revolution if the top players want to stay top players.
Thank you all for the congratulations, it's a great feeling. I've met some great people on this event as well, hope to make it to next SNG. Until then, SMOrc
