Ditto to everything I said about Plains. This is probably a recurring theme, so I'll just post the rest of the basic land. I will say this: I want some full arts of all of these... In addition, it appears that John Avon is doing one of each land type, and Richard Wright is doing two of each land type. Well, more accurately, one of the lands by Richard Wright for each color is the reprint from the original Ravnica block and the other is new artwork for RTR.
I can't read the numbers off these... I just assume Gatherer has them in order. Anyway, fourth one is the reprint.
Anyone who thinks Grove of the Guardian is pointless, obviously doesn't know green/white decks, and definitely doesn't understand the Selesnya mechanic "Populate".
