Herald of Slaanesh

A cost reducer built to be dropped early and then quietly retired from the plan, which is precisely its function. The italicized "Locus of Slaanesh" line is flavor dressing on a static effect: a standing discount on every Demon spell you cast afterward, not a one-time rebate, so the value compounds with each Demon that follows. The denser your tribe, the more this 2/2 pays for itself across a game. Pairing that discount with haste for your other Demons converts the back half of a tribal curve into immediate pressure rather than telegraphed sorcery-speed commitments, shrinking the window opponents usually get to answer a fresh fatty before it swings. The tension is deliberate: the body itself does nothing on the board, so the whole design leans on reaching the payload it enables while contributing nothing to the fight in the meantime. As an engine it lives or dies by tribal density, glue rather than a finisher, the kind of low-cost enabler a Demon deck wants down early precisely because it makes everything after it cheaper and faster.
