Resolve all remaining Exquisite Blood triggers, causing you to gain that much life, choosing not to pay for the Trudge Garden triggers in between.
This elegant loop turns a simple sacrifice into a self-sustaining engine of life and death, entirely fueled by Ashnod's Altar converting our boards into mana. Mirkwood Bats acts as the pivotal bridge here, effortlessly weaponizing every single token created or sacrificed to drain our opponents. That life loss immediately feeds Exquisite Blood, driving our life total upward and triggering Trudge Garden to churn out fresh 4/4 green Fungus Beast creature tokens with trample to keep the altar fed.
