Land Destruction:
4 Army Ants
4 Stone Rain
4 Choking Sands
4 Desolation
Critters
2 Tar Pit Warrior
2 Fallen Askari
2 Wall of Corpses
2 Suq'Ata Lancer
2 Burning Shield Askari
Misc.:
4 Miser's Cage
Mana Sources:
11 Swamp
7 Mountain
3 Sisay's Ring
2 Fire Diamond
4 Charcoal Diamond
3 Mana Prism
The deck usage should be pretty obvious, as you should try to cast
Desolation with A Fire Diamond and 2 Charcoal Diamonds, or some
other way of producing each of these mana amounts 1BB, 1BR, or 2R
Then you can cast everything without losing lands to Desolation, and
they can be saved for the Ants. Wall of Corpses is good for incoming
Wildfire Emmisarys, and Tar Pit Warrior's Drawback should be trivial
when your opponent has little to no mana.
