Lush Growth

One green mana turns a single land into three basic types at once, and the design economy behind that rate is where this card earns its place. Most green fixing that came before paid for color access incrementally: a creature that fetches one land, an Aura that adds a single type, a search that thins the deck a card at a time. This one collapses Mountain, Forest, and Plains onto a single permanent, which means it does more than smooth a draw; it actively powers cards that count basic land types. Anything that wants a Mountain you do not have, a spell that cares whether you control a specific type, a domain spell tallying how many types you control: the enchanted land answers all of them simultaneously. The trade is structural. It is an Aura, so it commits a card and sits exposed to enchantment removal, and it does nothing to fix a land you have not drawn yet. It also overwrites the land's existing types entirely rather than adding to them, so the type set is exactly three, no more. That narrowness is what pays for the reach: instant three-color access off a one-mana investment, but only on a land already in play, and only those three colors. It is fixing built for decks that care what their lands are called, not just what they tap for.
