Lyev Skyknight

The detain mechanic was the Azorius answer to a structural problem: how do you make a control guild aggressive without giving it hard removal or counterspells stapled to bodies? Detain is the compromise, a temporary lock that strips a permanent of attacking, blocking, and activated abilities until your next turn, and this is the cleanest aggressive package built around it. The enters trigger neutralizes a blocker the same turn a 3/1 flier comes down, so the detained creature sits useless while the Skyknight starts the clock from the air. The body and the ability point the same direction: detain removes the obstacle, the evasive 3 power exploits the opening, and the window closes right as you would want to attack again. The asymmetry is the elegant part. A blunt tempo card would tap or bounce; detain leaves the permanent on the board, fully owned by the opponent, just inert for exactly one cycle. That makes it answer planeswalkers and problem permanents as readily as creatures, while costing nothing in card economy to the controller. The fragility (one toughness, dead to almost any burn or reach blocker) is the price for cramming evasion, a clock, and a one-shot removal-adjacent effect onto a three-drop. It is the rare guild-mechanic showcase where the keyword and the creature were clearly designed as a single thought rather than a body that happens to carry an ability.
