By equipping a creature with both Thornbite Staff and Nazgûl Battle-Mace, you transform it into a lethal engine of destruction, granting it the deathtouch needed to instantly kill anything it damages. Arcane Teachings provides the essential ranged damage capability by giving the creature its own tap ability, which Thornbite Staff then immediately untaps whenever a creature dies. This creates a devastating loop where you can machine-gun down every creature your opponents control, while the menace, annihilator 1, and permanent-stealing abilities from Nazgûl Battle-Mace completely lock down the board and punish any new threats that try to enter.
