How it works
Activate Quest for Pure Flame by removing four quest counters from it and sacrificing it.
Cast Malignus by paying 3. It'll enter with power equal to half the highest life total among your opponents, rounded up.
When Malignus enters, Champion of the Path triggers, causing Malignus to deal damage equal to its power doubled to each opponent due to Quest for Pure Flame.
