Jeskai Runemark
A common Aura built to teach a wedge's color pairings through reward rather than restriction: the +2/+2 is yours no matter what, but the flying only comes online while you control a red or white permanent. That single condition is the whole pitch. Cast this in straight mono-blue and you have an overcosted pump enchantment; add even one red or white permanent and you have evasion stapled to a meaningful body boost. Each member of the runemark cycle worked the same way, handing its enchanted creature a stat bump plus a keyword gated on controlling a permanent of one of the wedge's flanking colors, nudging players toward the intended multicolor decks without ever forbidding a monocolored build. The situational flying is also what keeps the card fair. Auras carry the two-for-one risk baked into the type (one removal spell answers both the enchantment and the creature under it), and this one adds a second point of failure: the flying clause can switch off mid-combat if your last red or white permanent dies before damage. It asks you to hold a board state, not just resolve a spell, the kind of low-stakes deckbuilding lesson a common at this rate is meant to deliver.
