Enact a new rule “Meddling”:-

Each Sport may have Meddlings. These are listed in the Sport’s Form Sheet as “Meddling (X)”, where X is the name of each Meddling.

A Punter who has at least 10 Readies may plan a Sport’s Meddling, applying it to a specific Participant in a single, specific Event of that Sport (identified by the Sport and the date on which it will occur) that has not yet occurred, by privately informing the Bookie of this.

In “Form Sheet”, to the end of the paragraph beginning “The Bookie may generate the resolution”, add:-

When generating the resolution of a Sporting Event, the Bookie applies all Meddlings that were planned against Participants in that Event. (If the same Meddling would be applied multiple times to the same Participant in an Event, it is instead only applied once.) For each Meddling that is planned for an Event, the Punter who performed it loses 10 Readies at the start of that Event.

To the “Nomich” rule, add:-

Meddling (Transmute): Whenever the Meddled Participant is dealt an Ace, it becomes a King of the same suit instead.
Meddling (Drop): The Meddled Participant is dealt one additional card, then their highest rank card (ties resolved at secretly random) is discarded.
