Hey there, I know not many people like trading away Legacy cards for standards, but I figure it's worth a shot. I'm attempting to build a Goblin deck, so I need some Goblin Piledrivers, Wastelands, Plateaus, and Rishadan Ports. (Also feel free to check out my wish list, which has some other stuff listed.) I have plenty of Standard stuff, mostly from Theros including:
Master of Waves
Elspeth, Sun's Champion
Stormbreath Dragon
Hero's Downfall (2)
Thassa, God of the Sea (2)
Xenagos, the Reveler

Also,
Jace, Architect of Thought (2)
Scavenging Ooze (2)
Goblin Sharpshooter (3)
Boris Reckoner (5)
Steam Vents (2)
Mutavault (2, I'd prefer not to trade, but would be wiling to consider)

Here's my Deckbox profile: http://www.deckbox.org/users/xr775
It's all up to date, minus a few pending transactions.

Also, I'm accepting Paypal for any of it :) Please feel free to contact me about anything, all offers are at least looked at with no hard feelings.

Thanks for looking and happy trading!

A little bump never hurt anyone.
