Tactics for the Swamp (Fortress).

Start with Tazar. (see templates smki and 8mm6) - there is an opinion that he is the best hero for random in the entire game. There were few instances of his defeat in melee. He can only be taken down by magic. But it can either be deflected by resistance or Tazar himself might have some :) Or simply a cloak or sphere; then it's very problematic to win against him.
On the 1st, we get hydras. (it's never happened that they didn't appear :) in the fort or if lucky in the castle.
On the second, these hydras (2-3) together with Tazar take any wyvern tree. (finding it is the main task) but on these templates it is solvable. Then with a super cool stack of upgraded wyverns (there were games with 50+ by the second week, +angels from conservatories), the Dragon Utopia is taken either at the end of the second or beginning of the 3rd. And then rush to the opponent.
