Moon-Eating Dog

A plain body with a conditional keyword tacked on, built for a product designed to teach two players a specific rivalry rather than to slot into any wider constructed pool. The flying clause only switches on while you control a Yanling planeswalker, which tells you exactly what this creature was meant to sit next to: it is a supporting piece in a fixed deck, not a card evaluated on its own merits. Strip the condition away and you have a 3/3 for four mana, the kind of rate that would never earn a slot anywhere on its own. The design logic is narrative, not competitive: the card ties its upside to a named ally so that the intended deck plays as a coherent story, with the Dog gaining evasion precisely when its planeswalker is on the battlefield to protect. That is a fine goal for a two-player starter product and an awkward one everywhere else, because outside the specific shell the printing was built around, the flying almost never comes online. Read it as a curiosity: a creature whose keyword is a leash to a particular walker, honest about what it is and uninterested in pretending otherwise.
