With 5 cards, you have a 3 in 5 chance of being able to choose an bumhole (meaning in turn you can do 10*3/5=6 damage for every 4 scoops you earn on average, plus whatever extra you get from drawing destroyers, thieves or shotguns)

As shotguns aren’t an option, you have a 3 in 4 chance of being able to choose an bumhole, thus doing an average of 7.5 damage per 4 scoops you earn, plus any extra from other attack cards, making it closer to 8 damage per 4 scoops.

The second strategy for the week is to not play destruction cards at all, and just earn as many scoops as possible to offset anyone who doesn’t play along. Almost making it a prisoners dilemna situation – don’t screw each other over for potential mutual advantage or screw each other over and end up with a dice roll finish. In actual practice though, that would be very boring and the opposite of the intended effect.
