Counter-heroes in duel mode (3.1).

I'm curious, what is Andrey K's account name on Uplay? Regarding Hagga, yes, she might be able to counter Airie and Ossira as well. Her ability with Cyclops, which seems to be on the second level of Fury, is very interesting. You can boost them and throw them at ranged or pre-ranged fortifications, and the opponent will either not be able to retaliate at all (for Airie) or will be able to do so only rarely (Ossira). But Airie has infantry and air units, which are the most "formidable" in 3.1, and Ossira also has her own super arguments. This pairing is quite specific (Airie-Hagga), and if the opponent doesn't know how to play, you can certainly gain an advantage. I remember once almost losing to Airie in this pairing, but... my armored units crushed everyone. This is the old, well-known pairing of Deidra-Ora. Everyone complained about it in 3.0, but this pairing offers a lot in terms of tactical diversity (I counted three or four tactics just for Deidra). What's the best way to play her, and does Deidra have any chance at all? These are the questions.
