Nyxborn Triton

The bestow mechanic answers a problem that has dogged Auras since the beginning: a normal enchantment is a two-for-one waiting to happen, because removing the enchanted creature eats the Aura along with it. Bestow refunds the enchantment as a creature instead, so the downside that has always made Auras risky is partly bought back. Cast cheaply, this is a defensive body whose toughness blunts an attack; cast for its bestow cost, it becomes a permanent stat boost that outlives whatever it was stapled to, dropping back into play as a creature the moment its host dies. That non-destruction clause is the whole pivot, and it is what separates bestow from every straight Aura before it. The +2/+3 grant skews toward survivability over reach, which suits a color that would rather stall a swing than push damage through. As a common-rarity expression of the idea, it hits the cleanest version of the pitch: a low floor when the game is young, a flexible ceiling when it stabilizes, and no board state where the card is genuinely stranded. It was never built to be flashy. It was built to be the card you are always content to hold, useful on turn three and useful again ten turns later.
