Many cards of this sort usually have a clause that says "in addition to its other types".
Some players don't think that much about it unless it gets to cards like Sea's Claim, but this one isn't this kind of card, since you're expected to cast it on one of your lands as a mana fixer.
I feel like this should have a reminder text like:
(It loses the types it previously had.)
I can imagine casual games where something like an island or a swamp (or Cloudpost) with Lush Growth attached to it was still tapped for its respective mana (or counted as a locus - or whatever it had been before).

Anyone else realize this was partially a counterpart to Sea's Claim and Evil Presence? It just so happens to cover the other three land types.

It's an ok card. I'd much rather run Abundant Growth. On the other hand, this can be used offensively to get rid of an annoying land that an opponent controls, such as Grove of the Guardian.

Kind of a crappy card. At least it gives budget players an option to play some kind of crappy zoo deck. Meh your spending 1 card and early game mana to enable Wild Nacatl and prevent color screw. Like most cards in magic, this was probably designed for limited.
Multiples of this would be not good to see at all. Slipping in just 1 would be bad as well, because your likely not going to see it when it counts, early game.
But then again you still have the option to hose a nonbasic land opponent controls if you pull 2, or do not need to self cast. Got to give it points for that. Bonus if your playing against

Seems like a decent way to enable forestwalk if you're rocking an Elvish Champion.
