Not being a real Domination player, I can’t say should be posting in here, but i will anyway:

bumhole cards are necessary, as much as any other card. Why? Because it puts the guy in front in fear. It adds a lot of last-minute strategy to it. You don’t hit the lead until the absolute last minute to make sure no one bumholes you, or you jump so insanely far into the lead it’d take a deck of the bastards to bump you down.

My five cents.
