After a couple of games on this map, I came to the conclusion that any melee-focused castle consumes timer resources compared to a ranged castle. Magogs, gremlins, and marksmen can quickly eliminate 5-6 guards in a row on day 3. Melee units (at least, I don't know how to fight with wolves quickly without losses) certainly slow things down, and in potentially difficult battles, they will spend more seconds on the first day. And the main disadvantage of playing as Tyras is problematic battles on days 121-122 – when the same Inferno can capture wings guarded by 9 Chaos Hydras with minimal losses. But with Tyrax, it seems you have to wait until you create a second attack stack; this hero can determine the game's pace.

And in general, in my opinion, Tavern is the strongest here. :D
