3rd annual offline tournament "Best of the best"

Hold a "master class" if you can. After all, all these tournaments and their discussions exist so that one's experience can grow.
What does it mean to "put any Necromancer into a Castle"? Are there any rules for this, or is it a matter of chance? If we feed one of our Necromancers to the computer, what guarantee is there that he will appear in the computer's tavern? After all, to use your scheme, you'd need to kill that Necromancer in the Castle every time. What then? Dig him up, feed him again in battle, and wait for the computer to buy him? Or how?

You take a sniffer, skip a turn, and at the start of the next day, check who is in the computer's tavern.
If it is not a Necromancer (or whoever you need), but for example, some Mage (never mind - Astral), if you roll back one turn and buy Astral, the computer will get a different Mage.
What to do?
You need to roll back, buy all the Mages, and stuff them into your own towns. Then check: did a Necro appear for the computer? What, still some random guy? Yes, roll back, buy up all of that class again.
If it doesn't work, and your towns are full, "work on" the next computer.
If a Necro finally appears: dismiss the Necro you want to give to the computer, buy up all other Necros for yourself.
If you succeed, for example, in forcing Vidomina into the computer's tavern this way, then if you approach his town closely with an army and give him gold, the computer usually hires two heroes, putting the hero with lower stats outside and the one with higher stats and an army inside.
If Vidomina comes to him with higher stats than the hero in the adjacent slot, he will buy her.
If she has lower stats than, say, his main hero sitting in the town, then Vidomina will remain "outside" (which is desirable, as it's easier to pawn a Necro off on one of five computers than one of four, but not mandatory, as other computers remain).

Next: you attack Vidomina, lose, but clone the army.
Well, as I thought: for example, you have 100 skeletons and a Bone Dragon, Medal of Vulnerability, and all spells from Pandora's Box. And Nimbus (my green player's Nimbus is first) has Scouting and knows nothing beyond level 1. You clone the skeletons, lose the army, and retreat with the Medal and Bone Dragon. Nimbus raises however many - (30Necro+10Cloak+15Boots)%x2x100=110 skeletons.
Then attack, beat him, he should make a clone.
You, with the dismantled Cloak of the Undead King, raise 100%x2x110=220 skeletons. So in one day, you simply doubled your entire skeleton army from nothing. And this is on a bad day, when you only stuffed one Necro for one computer.
And so you keep spinning this carousel until the time comes to raise zombies.

By the way, this manipulation has already been banned on Portal ;)

Incidentally, it doesn't have to be a Necro for the computer. If there are two Cloaks of the Undead King, then from a hundred, a non-Necro computer with the Cloak of the Undead King raises 60 skeletons, your Necro with the dismantled Cloak of the Undead King then raises 120... So you grew the army by 20%...
