Victor, Valgavoth's Seneschal

The trigger counts, and the counting is the whole design. Most "escalating" enchantment payoffs give you the same effect each time and reward you for hitting it more often; this one hands out three distinct rewards in sequence, gated so that only the first Eerie trigger of a turn does the cheap thing, the second does the mean thing, and the third does the game-ending thing. That structure asks a specific question of the deckbuilder: can you generate three separate enchantment-enters or Room-unlock events across a single turn, not just repeat one? Getting there once nets you a graveyard reanimation with no color, cost, or type restriction on the creature, which is a lot of reach for a three-mana body to be pointing at. The counter resets every turn, so the engine is built to be re-primed rather than exploded once and abandoned, and the surveil-first ordering is doing quiet work too: it lets the first trigger fill the yard that the third trigger then robs, so a single turn's worth of Eerie activity can dig up its own reanimation target. It sits in the black-white enchantment-attrition lineage that grinds through discard and recursion rather than racing, and the tiered payoff is the clearest statement yet of what that archetype wants: not one big enchantment, but a steady drip of them.
