By arming a creature with both Viridian Longbow and Gorgon Flail, you grant it a fatal ranged touch—turning any ping it makes into lethal deathtouch removal. Thornbite Staff completes the masterpiece by giving that same creature its own active sniping ability alongside a crucial passive trigger that untaps it every single time a creature dies. Because deathtouch ensures that even a single point of damage destroys its target, Thornbite Staff's untap ability triggers immediately, allowing you to repeatedly clean the board and lock your opponents out of ever keeping a creature alive.
