Valkyrie Aerial Unit

Affinity is almost always a red-white-black story: cheap artifacts, aggressive bodies, mana that scales downward as your board grows. Putting the mechanic on a blue flier with surveil bends it toward a different axis. The printed cost of seven mana is a fiction the discount is built to erase, so the card asks a controlling artifact deck to already have a board of Constructs, Treasures, Clues, or similar filler before it becomes a real play. The surveil-2 trigger is the reward for that setup: not raw card advantage, but library sculpting that feeds a graveyard-matters or top-of-deck plan the moment the body lands. That combination is the tension worth noting. Affinity's traditional home wants the artifacts cheap and expendable, cashed into damage; this creature wants them present and stable, functioning as a permanent-count engine while it draws down its own cost and refines the next few draws. A 5/4 flier that can arrive for a handful of mana is a fine clock, but the sculpting matters more than the swing here: this is a blue payoff for an artifact density that blue rarely builds on its own. The card sits at the seam between two archetypes that do not usually share a color, which is the most interesting thing about how it is put together.
