Military wing is so good against House of Lancaster because they get bonus HP with the Lords of Lancaster, and with boot camp you can combat that with your own bonus HP.

Horsemen are great against Yeomen as long as there aren't spearmen; even Hobelars can't keep horsemen off the Yeomen.

If you go military wing against House of Lancaster, definitely don't go for a third TC.

A fairly popular strat is to target fire Lords of Lancaster with intent because of the raw HP increase they provide.

Camel Archers do exactly the job they were meant to do: clear out the initial mass of spearmen. They get so much bonus damage against them, and they attack faster than normal archers. With four Camel Archers, you're basically doing the job of ten archers, but more effectively because you attack much quicker and have more health. Yemen, in bulk, are able to take down Camel Archers quite quickly, but by the time the Camel Archer goes down, so many volleys have been pumped into them, meaning the volleys that could have been spent elsewhere kind of missed on the Camel Archers.
