This clever setup hinges on a self-sustaining loop of damage, card draw, and counter generation. By equipping Walking Ballista with Snake Umbra, its damage-dealing ability is upgraded to also draw you a card whenever it strikes an opponent. That newly drawn card immediately triggers Lyla, Holographic Assistant, which replaces the counter you just spent to keep the engine rolling. Together, these three cards create an endless cycle that lets you mow down your opposition and draw your entire deck in the process.
