[Tournaments HMM V OFF] "Lord of the Golems"

Well, it seems like it's possible now. My result wasn't the worst – 12 days. I could have done it in 10-11 days, but I didn't have time to replay.

What, what??? 12 days – is that even possible in this tournament? Or am I missing something? I defeated that Golem Lord on day 66; I could have done it earlier. I could have, but I didn't. Now, let's get to the discussion:)
I defeated those golems on day 8. Uranist was a little ahead of me. They are easily defeated with one Obsidian Gargoyle. There's an interesting tactic called the "evasion tactic." The main thing is that your creature's speed is 3 or more higher than the enemy's, and its initiative is somewhat higher. Then, with this gargoyle, you just fly around the entire field, making sure the golems don't get within 1 step. We also attack the Zealots on silver. Free experience is a good thing.
There's one bug there. Well, I think everyone noticed it. It's the unprotected Gem Mine; the Zealots are positioned awkwardly there.
I didn't develop the Undead faction much. By the end of the game, I only had Archers, Zombies, Specters, Vampires, and Death Knights. The only benefit of the Undead was that they captured the Sawmill, Mine, and Crystal Mine (Oroy didn't go for the Forest Archers at all; they were defeating my Golems even in the late game, 80 creatures at a time).
For some, this is normal, but for me, having Colossi on the 3rd week, right on the 20th day, is very cool! Especially on a hero. In Veteran difficulty, they only appear on the 4th week for me.
I couldn't defeat the Golem Lord! With 8 Titans, 30+ Mages, and many Golems! I had to replay a bit. They kept reaching my units and defeating them with one hit! And I couldn't finish them off; there were too many. But after waiting just a week and a few days, I defeated him! And I completely crushed him! I only attacked the Golems. Then the Golems. And with my units, I destroyed the cart first.
I've lost my inspiration to write; maybe I'll say something else later:)
Thanks again; the tournament is really interesting!

P.S. I used to underestimate the Fire Trap. Now I understand that with good spellcasting and skillful summoning magic, it's just a level 11 creature. I mined the map; no one survived!
P.S. P.S. No, explain how it's possible to complete this tournament in 20 days?!
