Vedalken Entrancer

Two cards a turn, for one blue mana, off a body that survives most early aggression: this is mill at the pace of patience, not the pace of a combo kill. The 1/4 frame does the real defensive work here. It blocks the small attackers a deck wants to ignore while it grinds, and it asks for no protection beyond keeping a single blue source untapped each turn. The cost of that resilience is the rate. Two cards per activation is glacial when a typical library runs decades of turns deep, and the tap requirement caps the engine at one activation a turn even when the mana is there. That makes this a card built for an era when milling out an opponent was treated as a slow inevitability rather than a fast threat: a wizard you deploy, leave back, and tick away with for as many turns as the game allows. The lineage runs through the patient end of blue's library-attrition designs, the ones that grind rather than detonate. Where later mill leaned on big one-shot chunks or self-mill payoffs, this is the recurring-tap school: small, repeatable, and contingent on living long enough to matter.
