Rulings

  • 2025-06-06

    If Maester Seymour is no longer on the battlefield when its first ability resolves, use its power as it last existed on the battlefield to determine how many +1/+1 counters to put on the target creature.

  • 2025-06-06

    Monstrous isn't an ability that a creature has. It's just something true about that creature. If the creature stops being a creature or loses its abilities, it will continue to be monstrous.

  • 2025-06-06

    Once a creature becomes monstrous, it can't become monstrous again. If the creature is already monstrous when the monstrosity ability resolves, nothing happens.

  • 2025-06-06

    The value of X is determined only once, as Maester Seymour's last ability resolves.
