Which is a shame. I prefer alternate rules which change the plus cards rules to allow plays such as more +2’s added on top, color appropriate skips and reverses, wild cards and +4’s.

Wild cards simply pass the draw to the next player. Basically every face card can be used to counter draw cards, though usually by adding more danger. It just adds a level of skill and planning over a game where getting randomed by a +2 or +4 is just a loss.
