King of the Oathbreakers
Phasing as a defensive mechanic is one of Magic's oldest ideas, but it was almost always something you did to yourself as a cost. Here it becomes a reactive shield that a whole creature type wears at once. Point removal, a targeted bounce spell, an aura, even your opponent's own beneficial targeting: any of it sends the Spirit out of reach until your next turn, and the phased permanent slips back in intact rather than dying or getting exiled. The trick is that phasing out is not a "may," so this cuts both ways: an opponent who wants a Spirit gone temporarily can force the issue, and your own targeted pump or protection spell whiffs on a creature that vanishes in response. What ties the mechanic to a payoff is the phase-in trigger, which mints a flying Spirit token every time one of these creatures returns. That turns each attempt to interact into a two-for-the-price-of-one: the target survives the turn and you bank a body for the next. Built around a wide Spirit board, the whole tribe becomes a shifting target that answers spot removal with growth. The 3/3 flying frame is modest for the color pair, but the body is not the point; the point is a lord that punishes single-target interaction structurally, converting the opponent's spells into your board presence.
