Rune

Rune is an aura enchantment type introduced in Kaldheim.
==Description==
Runes can enchant any permanent, though they only provide an effect if attached to a creature or equipment. When attached to a creature, they give it a specific ability. When attached to an equipment, they allow it to grant the same ability when equipped to a creature.
The Rune subtype doesn't have any special rules meaning, but there are a couple of cards that care mechanically about Runes.
===Storyline===
The Kaldheim runes are linked to blessings of the gods.
==Development==
Runes were initially conceived as upgrading your Equipment by carving runes into it. During development it was found that an Aura that only enchanted equipment, both of which were not common in decks to begin with, was too narrow for players to justify using. R&D changed Runes to "Enchant permanent" with abilities that focused on equipment and creatures so the Runes would be viable enough to go in decks.
