Nimbus Naiad

A single Aura that dies with its host is a two-for-one waiting to happen, and for two decades that risk kept buff-Auras on the margins of Constructed play. This nymph answers that math by refusing to commit to being an Aura at all. Cast it for its base cost and you have a 2/2 flier doing honest work on an empty board; pay the bestow cost and you pin +2/+2 and evasion onto an existing threat, with the safety net that when the host dies the enchantment falls off and stands back up as its own 2/2. The keyword files off exactly the vulnerability that made Auras dangerous to run. What you pay for that insurance is tempo: the bestow cost is steep, and it only earns its keep once you already have a body worth dressing up. The real decision is reading the board (which mode does it reward right now), backed by the promise that guessing wrong will not strand the card. As the clean middle rung of the flying-nymph cycle, it is the least flashy demonstration of what bestow was built to prove: that attaching a buff to a creature can be safe enough to do at sorcery speed, because the clean blowout Auras always feared is the thing the mechanic quietly removes from the table.
