Okay, so we've decided on a couple of heroes from Or-Erin, right?
How about this scenario, for example. In my opinion, mages should always take down Fury or Megera, while the Armageddon's Blade cart dies.
And here's another interesting pair: Deleb and Deidra. Of course, the opponent wasn't that strong, but it still tested the old Deleb defensive tactic. With Deidra, you need to cast mass light spells and add vampirism to the dragonlings. This pair is notable because it was decisive in the last real tournament for duel matches in version 3.0. Back then, Deleb won.
