Vectis Agents

Evasion that taxes itself is the unusual lever here: paying two mana slips the 4/3 through unblocked, but it arrives as a 2/3, shrunk by its own attack. That tradeoff is the entire engine. Most unblockable enablers either cost nothing on the board (an aura, a one-shot spell) or simply ignore your creature's size; this one charges a toll against the very swing it permits, which keeps the body honest. You are not pushing four damage past a wall for free: you are choosing between a contested four and an uncontested two, and that choice resets every turn the mana allows. The result reads less as combat math than as a repeatable connection machine, a body suited to effects keying off damage dealt to a player: a poison or infect rider, a saboteur trigger, any payoff that cares about hitting face rather than how hard. The artifact type is the quieter wrinkle, opening the card to graveyard recursion, sacrifice payoffs, and artifact-creature synergies that have nothing to do with its blue-black casting cost. Modest design, but clean: a repeatable unblockable rider with a built-in cost, rather than a finisher whose evasion comes free.
