By using **Donate** to hand your opponent a **Blightbeetle**, you weaponize its static ability—which prevents your opponents' creatures from ever receiving +1/+1 counters—against their own mechanics. This clever exchange turns **Umbral Collar Zealot** into an infinite sacrifice engine with any undying creature, because the Beetle completely shuts down undying's self-counter penalty. As the creature repeatedly dies and returns to the battlefield without ever accumulating counters, you generate endless leaves-the-battlefield, entry, death, and sacrifice triggers alongside an infinite amount of surveils.
