Wild Growth

Yes, Llanowar elves may be superior to this in many ways, but I believe many of us are forgetting about our friend the Arbor Elf. If you boost up your lands with cards like this one and untap them with Arbor elf it can be very efficient.

I also would generally prefer to play Llanowar Elves instead of Wild Growth, but the fact that Wild Growth can produce mana the turn you play it can make it more useful than the elves in certain situations. I have both in my BG agro deck and it allowed me to do this the other day: T1 Swamp, Dark Ritual, Buried Alive, drop Brawn and 2 Vengevines in graveyard. T2 Forest, Wild Growth the Swamp, tap it to lay Llanowar Elves and Carrion Feeder, put both Vengevines into play and attack for 8 trample, then sac them to the Carrion Feeder. T3, Forest, Primal Forcemage, Ornithopter, put Vengevines into play and attack with them. They are now each 7/6 from the Forcemage. That's another 14 trample. That was the end for my opponent. Even if it wasn't, my attack engine was already up and running now. I could've sac'd the ornithopter, Llanowar elves, and both Vengevines to the Carrion Feeder, putting 4 more +1/+1 counters on it, then drop another 2 little creatures next turn to bring the Vengevines back out again. It's a nasty little loop, and it would've taken me at least one more turn to do it without the Wild Growth.

This is a pretty good card. I use it in my solid green decks with llanowar elves to speed the decks up. In multi colored decks I go with fertile ground. It costs one more but the ability to choose any mana type is worth it. I'd say wild growth is a good card, just depends on the deck and how it is used.

I'd take Llanowar Elves over this any day. Elves can attack, block, get bigger via elf enhancers, and you can choose whether to use it whereas here you might take mana burn if you don't use that extra point of mana.
