Aragorn and Arwen, Wed

Unlike Solitude, this six-mana creature supplies neither immediate interaction nor cards; a board-dependent anthem is too slow for credible Modern adoption.

Could be wrong if An unshown efficient creature-token shell or mana-cheating package could make its repeatable attack trigger relevant.

Six mana for a board-dependent combat effect is far below Legacy's efficiency bar, and its legendary status adds Karakas exposure.

Could be wrong if A new fast Selesnya swarm shell with unusually reliable acceleration could create a narrow home.

A repeatable team counter and lifegain payoff has a real go-wide home, but six mana, no token production, and no card advantage make it replaceable.

Could be wrong if Token density and access to haste/protection determine whether attacking once is realistic before removal.

A 3/6 vigilance body that permanently grows an existing board and gains substantial life is a premium stabilizer, though weak when cast alone.

Could be wrong if Unknown speed, removal, and archetypes could make six mana or the need for other creatures substantially worse.
