How it works
Kill Ondu Spiritdancer.
Myrkul triggers, creating a token copy of Ondu Spiritdancer that is an enchantment.
When the token Ondu Spiridancer enters the battlefield, it and Setessan Champion trigger.
Resolve the Setessan Champion trigger, putting a +1/+1 counter on it and causing you to draw a card.
Resolve the Ondu Spiritdancer trigger, creating a token copy of itself.
Repeat from step 3.
This engine transforms the death of Ondu Spiritdancer into an explosive, self-sustaining loop by leveraging Myrkul, Lord of Bones to turn creatures into enchantments when they die. Once that first enchantment copy enters, Setessan Champion turns every subsequent loop into a steady stream of card draw and +1/+1 counters, letting you safely dig through your deck. Meanwhile, Ondu Spiritdancer's own enchantment-copying ability triggers off the freshly minted token copies, creating an expanding wave of new triggers that feed back into Setessan Champion.
