Sailmonger

Most evasion outlets are private engines: you pay the cost, your attacker gets flying, your opponent's ground blocker watches it sail over. This one tears the fence down. The activated ability is open to the entire table, which inverts what evasion is supposed to buy. An opponent can lift their own attacker over your ground blockers, or, anticipating your alpha strike, pay the two mana to keep a defending creature relevant against whatever you were planning. Whoever activates it pays the cost, so the effect reads less as an asset than as a public utility bolted to a 3/3 body. That open access is the reason the stats sit where they do: a creature with these numbers and a private flying-granter would be a one-sided combat engine and priced accordingly, while a shared one needs no such tax. It comes from an early-era experiment in Human Mongers, all built around abilities deliberately stripped of ownership, usable by any player at the table. The quiet conclusion that line of design reached is that an ability nobody owns is an ability nobody much wants to spend on: evasion matters because it generates tempo for one side, and an outlet the defender can reach for too gives that tempo away the moment it becomes worth pressing. The shared button is the whole idea, and it is also the reason almost no one ever presses it.
