How think about tatars or turks in game C.A civs?

Well... I usually played teutons in team game. but sometimes I need to play the civs that have good range and mobility. So I want to practice some C.A civs.

​

Mongols is best CA civs in post imp but I think in castle tatars or turks are better, mangudai need to time for gathering, and free thurmb ring or fatser golde miner good advantage using CA in castles.

But I wondered tatars and turks are good in team game for C.A civs.
