Discreet Retreat [Commander: Outlaws of Thunder Junction]

Enchant land
Enchanted land has "T: Add two mana of any one color. Spend this mana only to cast outlaw spells or activate abilities from outlaw sources." (Assassins, Mercenaries, Pirates, Rogues, and Warlocks are outlaws.)
Whenever you cast your first outlaw spell each turn, you draw a card and you lose 1 life.
