702.87. Level Up

Level up is an activated ability. “Level up [cost]” means “[Cost]: Put a level counter on this permanent. Activate only as a sorcery.”

Each card printed with a level up ability is known as a leveler card. It has a nonstandard layout and includes two level symbols that are themselves keyword abilities. See rule 711, “Leveler Cards.”

Some enchantments have the subtype Class and associated abilities that give them a class level. These are not the same as level up abilities and class levels do not interact with level counters. See rule 716, “Class Cards.”
