Random Magic Card Mashup gave me Llanowar Elves and Teramorphic Expanse. There's only so many takes on small mana producing creatures, so it's nice to see a new one. Also got rid of 'come into play tapped'. The Elves have summoning sickness and are vulernable for a round... there's no need to rub it in.

Fascinating. Yes indeed, this is a common one-mana accelerator that's not been seen before. The comparison to Llanowar Elves is very interesting. These can't attack or block after they tap for mana, but nor can they be burned. Eminently printable!

This is actually better in some decks then others, which is nice. Its a 1-mana accelerate for lands which is good.

But, being able to grab nonbasics is very powerful. Have them ETB tapped at least.

But they do enter the battlefield tapped, due to summoning sickness. You're asking for a two-turn delay. I don't know if that's really neccessary. I do admit, though, this is really strong. As it is, I think Llanowar Elves is too powerful for Magic. I've never like turn one accellerants.

I agree no further delay is necessary. This can still be burned the turn it's dropped. This is, however, halfway between Llanowar Elves and Birds of Paradise, thanks to the shocklands. (Every other nonbasic Forest ETBs tapped or equivalent anyway.) If this was in Standard with shocklands, it'd be a money uncommon or rare; otherwise it's fine as a common that happens to be awesome in Modern.

Dropping in extra lands is far more powerful then just mana dorks. This would essentially replace BOP in many legacy and vintage decks that want more ways to drop lands in, thinning the deck and having a less destructible mana in play.

Insults are not a good plan.

It can still only get forests, so Birds of Paradise have a nice place to live. (If you've got the true dual lands, well, power level is hardly an overriding concern now, is it?)

It's usually going to be better than the elves, though. It's very good. No doubt about that. ­Dawntreader Elk suggests this ought to at least have an activation cost. Sakura-Tribe Elder was very very good similarly - but did at least cost one more.

There's always something to be said about it being okay to have a card be better than every other existing card. It's bound to happen to every card eventually. I don't think any staple card is so sacred that it can't be quasi-obsoleted.

That said, you already know my opinion on 1cc Elves. I don't like them. I know many people who do, though, so I defer to those people.

It's easy for me to change this to 'basic' forest, since that's kind of the intent anyway, and I'm not a fan of Shock lands leeching bonus abilities. Most of the time I wouldn't bother, but the power level of this card is high, so I'll draw the line.

That said, I know many mono-green decks that play Elf over Bird for that extra point of power. This card, for example, won't be able to block an incoming Titan on round 7. That might seem like a minor concession, but I'm pretty sure that would mean game in many match-ups. To be honest, I kind of think getting the forest is worse than having a bonus blocker/creature to enchant/Overrun leecher. Green likes having creatures.

Some green decks like to have creatures, that is true. Some green decks would also rather have more forests then creatures.
