So, what else should Necropolis focus on when playing against Haven?

I would like to clarify this, as well as which artifacts to equip.

So, a counterspell is needed, although it can be dispelled by Warlocks. This means that only artifacts and leveling up remain.

I thought about this for a long time. And I realized that you can't just rely on a counterspell against a Warlock-Trickster. The whole point is that the Warlock, with the help of mentorship, can create clones with Armageddon and BDP and easily mow down any army. The question is, what kind of hero does Necropolis need, with shackles, to take out these Tricksters? The only problem is how to level up such a hero. And what is also important, which units to take and how many for such a hero.
