I managed to get my hands on 4 NM River of Tears, and am hoping to use them to trade into other Modern cards that I (and or friends) need, such as

Huntmaster
Restoration Angel
Bloodghast
Abrupt Decay
Olivia Voldaren
Sulfur Falls
Thalia
Reveillark
Spell Snare
Phyrexian Metamorph
Lavaclaw Reaches


Also always willing to look at other stuff.

I'd be interested if you see anything from you want
