Ronom Serpent

A 5/6 body whose entire combat profile is leased back to your opponent's manabase. It can only swing into a player fielding a snow land, which inverts the usual hate-bear logic: instead of punishing a strategy, it grants permission to attack only when the opponent has already committed to the very land type the creature is built around. The second clause is the harsher leash, a self-destruct tied to your own board: lose your snow lands and the Serpent goes with them. This is anti-build-around design, the cost-side of the snow theme made literal. Snow as a supertype was an experiment in conditional rewards, and most cards in that line offered upside that scaled with how deep you committed; this one runs the meter in reverse, handing you an oversized creature up front and then attaching maintenance costs that bite if the snow plan ever falters. What you get reads as a beater but functions as a hostage to land-type symmetry on both sides of the table, asking you to invest in snow lands not for value but simply to keep the thing alive and relevant. It is the rare design where the drawback is not a tax paid once but a standing obligation: a body that demands you keep feeding the archetype it belongs to or lose it outright.
