After half of dozen of games of DG at the Bootleg BOYL convention we had a few chats about house rules and came up with the following:
Critical Hits: Natural 1s to hit with Battle or Firing mean the target has a +1 to their D roll
Butterfingers: If a unit carrying a Relic takes a Wound then they roll a D6 and on a 1 they drop the Relic.
Leg it!: We let a unit exit any board edge with a relic. If they managed to get it back to their side however they could then re-enter play.
