Deputy of Detention

The O-Ring lineage keeps refining the same trade: a temporary exile in exchange for a body or an angle nobody has tried yet. Oblivion Ring took anything; Banishing Light dropped enchantments from its own removability; Detention Sphere added the same-name clause so one card could catch a swarm of identical tokens. This iteration keeps that same-name reach and moves the whole effect onto a 1/3 that can block or crew a Vehicle after the trigger resolves. The exile persists only while the Vedalken stays on the battlefield, and that fragility bites differently depending on what got caught: kill the 1/3 and any nontoken permanents it grabbed all come back at once, from a single removal spell. Tokens are the exception that sharpens the calculus, because a token that leaves the battlefield for exile ceases to exist as a state-based action; sweep a wide board of matching tokens and the answer is permanent even if the Deputy dies. The enters trigger reads "an opponent controls," which cleanly rules out any friendly-blink value; you cannot flicker this to hide your own board or re-aim it at yourself. The upgrade over the enchantments, then, is not the same-name clause (Detention Sphere already had it) but the packaging: white-blue gets a repeatable, tribal-relevant, crewable body attached to a token-sweeper, at the cost of stapling the answer to a creature's survival.
