Yarok, the Desecrated

Panharmonicon reworked and broadened: the doubling clause reads as a colorless artifact effect grafted onto a Sultai body, and that grafting is the whole design story. Where the artifact only doubles enter-the-battlefield triggers coming off artifacts and creatures, this widens the domain to any permanent entering: a land with a landfall-adjacent trigger, an enchantment that gives a bonus on entry, a token conjured mid-combat. The precise wording carries the weight. It counts triggered abilities caused by a permanent entering, so it doubles the enter effect of a hardcast creature and a token alike, and it stacks with the artifact for a third instance of each trigger. That is the axis every deck built around it runs on: a critical mass of enter effects (blink targets that draw twice, aristocrat drains that hit twice as hard, sacrifice fodder that pays out on the way in) turns each new permanent into two payments. The 3/5 with deathtouch and lifelink is not the engine, but it is not filler either; it blocks profitably against almost anything and quietly gains life while the value accrues behind it. Designers had circled this doubling effect for years as an artifact-slot build-around; committing it to a legend, on a body that defends itself, is what turned a niche interaction into a deck's reason to exist.
