+ * 701.28. Monstrosity
+ *
+ * 701.28a “Monstrosity N” means “If this permanent isn’t monstrous, put N +1/+1 counters on it
+ *         and it becomes monstrous.” Monstrous is a condition of that permanent that can be
+ *         referred to by other abilities.
+ *
+ * 701.28b If a permanent’s ability instructs a player to “monstrosity X,” other abilities of
+ *         that permanent may also refer to X. The value of X in those abilities is equal to
+ *         the value of X as that permanent became monstrous.
+ *
+ * * Once a creature becomes monstrous, it can’t become monstrous again. If the creature
+ *   is already monstrous when the monstrosity ability resolves, nothing happens.
+ *
+ * * 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.
+ *
+ * * An ability that triggers when a creature becomes monstrous won’t trigger if that creature
+ *   isn’t on the battlefield when its monstrosity ability resolves.
