They're meant to synergize with Deep, so building it with Deep monsters should get you somewhere, at least.

Judging by their narrow focus, it doesn't appear they'd be able to make a competent deck alone.

On a related/lore note: they're an interesting inversion of Dragon Knights. Perhaps that's why the archetype is meant to rely on Deep dragons.
