Noob custom campaign question (Komnenos)

So for me, on moderate, nikephoros has 2 heavy pikemen, a cataphract and his varangian guardsmen.

All I can find are 3 cbs, 2 ca, 5 legionary, 1 light cav, and Komnenos. Out of these, I can only transport 10, and I never both win the fight and have Komnenos survive. If I don't bring komnenos, I don't win either.

What am I missing? Is it my micro (basically non existent)? Any tips?

P.S I do know enough to try to directly go for the guardsmen but the pikemen always finish me before I finish both.
