I don't think Combrei is the most effective aggro deck, but this list is fine, playing some cards you don't really see anywhere else. Notes on some card choices:
Fresh Recruit - obviously a pretty bad card but I wanted at least two 1-drop creatures.
Splatter Tactics - a really underrated card, with a low cost that can get blockers out of the way.
Glorious Mistral - giving some of your bigger creatures flying can really get you over the hump.
Swift Subverter - Charge is one of the best battle skills, and sometimes you can wreck a good card in their hand. Also goes well with the Commando.
Alhed, Vanguard - ditto.
Listening Bug - this might be a bit of a meme, but I think this card is quite good - it will end up as a 5/5 most of the time, and seeing your opponent's hand can be quite valuable.
I wouldn't play this in Diamond 1, but still a lot of fun.
