Stack

Condition
This rule can be played any time

Description
After playing your first card, you may play a card of a value one above or below the card you just played. You may then continue playing cards of increasing or decreasing value until you run out of cards or reach Ace. You are not allowed to stack past ace (Two, Ace, King or King, Ace, Two). You must keep stacking in the same direction (Five, Six, Seven, Eight. Not Five, Six, Five, Four). All rules that apply to all the cards played must be completed before playing your next card. Hail the Bard is most notable for this. Stacked cards do not need to be of the same suit.

Failure
Stacking is optional, so there is no failure for it. Other rules may be broken while stacking, in which case those rules' failures would be used.
