They key to mirror matches is to attack the opposing Hound's Tooth until you can mark the opposing Razor Crest (usually via a Cad Bane special, calling your Razor Crest, targeting their Razor Crest). If you attack the other ships, HT will get turn meter and taunt before you can Mark the opposing Razor Crest. Your win chance will go way down in that case.
First capital ship turn should be to bring Ebon Hawk in. UNLESS your RC is marked already and has taken significant damage (been the target of opposing Executor's mass assist, for instance), in which case, heal/cleanse Razor Crest and wait until next turn to bring Ebon Hawk in.
