This lethal loop centers around Horobi, Death's Wail, whose chilling static ability transforms any targeted spell or ability into an instant-kill removal spell for creatures. By paying the cost to activate Deathbringer Thoctar's ping ability, you target an opponent's creature, which immediately triggers Horobi to destroy it. Because Deathbringer Thoctar gains a +1/+1 counter whenever another creature dies, the demise of the targeted creature replenishes the exact resource you just spent, allowing you to repeat this devastating process indefinitely to lock down the board and wipe out opposing creatures as fast as they arrive.
