Gyee headcanon 51th

Markus enjoys training with Bidziil, ironically, because of his indifference and quiet personality:

Markus can fully focus on his fight because Bidziil almost doesn't talk and can do it as a warrior and no a "commander"

Bidziil doesn't have the bias of other Oathblades soldiers, so he fights Markus like he always does against any foe.

Bidziil, like Markus, is also a legend so he can actually push Markus to his limits and vice versa, so both improve on their training.
