Currently Dogmatika is getting nerfed in Master Duel with the semi-limitation of Nadir Servant, while Labrynth is not getting any restrictions.
It's kind of a 'paid for your sins' situation. The Nadir Servant and Five Rainbow Magician hits both affect Labrynth; the top Duelist Cup deck used two of the latter, and the small Nadir package (1 Ecclesia, 3 Nadir, 1 Punishment) was being run almost ubiquitously in Labrynth too.
