Tend to the Kiln

When this enchantment enters, all non−Elemental instant and sorcery cards you own perpetually become Elemental kindreds in addition to their other types.

Whenever you cast an Elemental spell, put a flame counter on this enchantment. Then if it has three or more flame counters on it, remove them, conjure a card named Flamebraider onto the battlefield, and it gains haste and "At the beginning of the end step, sacrifice this creature."
