The text of the encounter card Desecrated Soil reads (in part):
Draw 3 encounter cards. Then, discard up to 3 encounter cards from your hand. [emphasis mine]
A literal reading of this card suggests you could choose not to discard any cards at all, but that wouldn't make any sense (keep in mind there's no hand limit for encounters). The best guess I can make is you don't have to discard below five, since that would just cause you to draw again anyway - but I can't actually think of any way for you to have fewer than five cards before playing this.
Anyone have any better idea? Is there any reason you would
