Counter-heroes in duel mode (3.1).

I watched the replays, it was very informative, and I learned a lot about the tactics for playing as Or and Dyra'el. However, I still have a question: how to defeat Shakk-Kurath, what tactics should be used against him? And another question, how to play as Deleb, what are her advantages? If you have any, please post replays with them. I don't know why, but yesterday in random battles, only demons were appearing, and twice I had my Deleb against Kurath (twice in a row). P.S. I don't know if you watched my replays or not, but Marbas defeated Or, and Nimus defeated Dyra'el. However, I can't judge the level of the opponents:smile32:. P.P.S. Regarding the children, I have two, one is 3 years old, and the other is one and a half, but my wife isn't around with a frying pan:D.
