An enchantment land, a card with both the enchantment and the land type, first appeared as a test card in the Mystery Booster set (Enchanted Prairie).
Players have often wondered if enchantment lands had been considered for the "enchantment matters" Theros block. Mark Rosewater admitted that R&D's experience with artifact lands (which turned out way too powerful) scared them off from even trying, especially with Constellation in the mix. It would have been a problem even if the enchantment land was legendary. Even one enchantment land would have forced development to raise the costs of all the cards with the Constellation mechanic.
Rosewater assumes enchantment lands will appear in a regular set one day (possibly in a supplemental set) but most likely not in a set where “enchantments matter”.
- Playing Enchanted Prairie as a land uses a land drop, the same as playing an artifact land.
