I would like to identify the name of a certain gameplay mechanism. It is fairly commonly seen but probably best illustrated with card games:
A game played with a pack of cards usually has card values ordered in the following way:
A > K > Q > J > 10 > 9 > 8 > 7 > 6 > 5 > 4 > 3 > 2
Sometimes the lowest-ranked card (in this case
2) is specially ruled to trump the highest-ranked card (in this case
A). Is there a proper name for such a mechanism?
