This lethal setup transforms any creature into a one-man firing squad by combining Vorpal Sword's passive deathtouch grant with the ranged damage-dealing abilities of Arcane Teachings and Thornbite Staff. Once you tap the enchanted creature to snipe an opponent's creature, deathtouch ensures it perishes instantly, which immediately triggers the Staff's untap ability to let you repeat the slaughter. The result is a total board-clearing lock that continuously mows down opposing creatures the moment they enter the battlefield, keeping your opponents completely devoid of creatures.
