Not too familiar with the Scars of Mirrodin cards thus far, but I've decided to make a Swamp/Forest deck from scratch. I'd figure I'd go ahead and ask your advice, just because I trust you guys on this sort of thing.

Two things to keep in mind as you read this: I'm focusing on quickplay/infect, and for a challenge, I'm doing it with only common/uncommons. So do me a favor and tear me a new one:

10 forests
10 Swamps
4 Lead Myrs
4 Copper Myrs
4 Blight Mambas
4 Plague Stingers
4 Corpse Curs
3 Contagion Clasps
3 Trigon of Infestations
2 Trigon of Corruptions
2 Wall of Tanglecords
