The wheel
Razz term
The wheel is 5-4-3-2-A — the best possible hand in Razz. Straights don't count in a lowball game, so a run that would be a made hand anywhere else is read purely as its ranks: the five lowest distinct cards there are.
It's also called a bicycle. Nothing beats it, and nothing ties it but another wheel.
