Here is a RG Land Destruction deck by MTGO player, "deluxeicoff."
LSV (Luis Scott-Vargas) recently talked about this deck on the official Magic: the Gathering website.
This deck is just trying to get some quick LD going while dropping some big creatures before you recover.
As LSV put it, "This is a very honest deck. All it's trying to do is play an Elf into a Stone Rain into a Blastoderm, with judicious use of burn to clear the way. Opponents can't cast spells if they don't have lands, after all."
The deck is fun and straightforward, so give it a try.
