Séance Board

A ritual engine that charges off attrition instead of ramp. The soul counters accrue passively, one per turn any creature dies, so the mana it eventually produces is a ledger of the game's carnage rather than a burst you set up in advance. That patience is the whole trade: its output starts at nothing and scales with a board state you often do not control directly, but a table full of chump blocks, sacrifice loops, and combat trades feeds it faster than any single-controller build could. The mana it makes carries two restrictions doing distinct work. The first is that it comes as a single color per activation, so it fixes deep rather than wide. The second, and the design's real intent, is the spell-type gate: instants, sorceries, Demons, and Spirits only. That clause is what pins the artifact to a specific graveyard-and-spellslinger identity rather than a generic mana rock, and it tells you exactly what the card was built to power. It is a slow rock that rewards a deck already committed to dying creatures and death-flavored payoffs, converting the inevitability of a grindy board into an ever-growing pool for the biggest instants, sorceries, and Demon and Spirit finishers a long game produces.
