Siani, Eye of the Storm
The scry-X trigger scales with the number of attacking fliers, which makes the reward loudest exactly when the deck is functioning as an aerial swarm and quiet when the board sputters. That is a tidier feedback loop than a flat card-advantage engine: the number it produces is smoothing, not raw draws, filtering the top of the library in proportion to how much of the attack is airborne. A five-flier swing digs five deep and lines up the next turn while the damage lands. The 3/2 flying body is not the point; the engine is. Partner is what widens the frame. On its own the effect wants a flying-tribal build, but the second commander slot lets it graft the scry engine onto a different color's plan: a green ramp partner, a white anthem partner, a black sacrifice partner, each turning an aerial assault into a filtering payoff for a strategy that would not naturally reach for a mono-blue flier lord. What the effect quietly banks on is that in singleton, board-state-scaled formats, consistency is scarcer than raw power. A repeatable filter that grows with the board over a long game is worth more than its printed rate suggests, and it rewards a deck that commits to keeping bodies in the air rather than trading them away.
