459. Step 1: The Combat Showdown Step

459.1. Combat will open in one of two ways: when a Combat and Showdown are staged at the same Battlefield and the turn player initiates the Showdown; or when the turn is in a Showdown Open State and a Combat is staged at the Battlefield where the current Showdown is ongoing. See rule 318. Cleanups for more information.
459.2. When Combat opens, it either opens with a Combat Showdown, or the current Showdown becomes a Combat Showdown.
