The "Legacy Championship Match" was originally contested in elimination tables match, wherein any person who breaks through a table with they're body is sent back to the lockerroom until only one remains as the winner.
However since 2015, it has decided instead in a gauntlet match, where only two competetors are in the ring at the same time. When one participant is defeated another comes out until a final winner is declared. That winner gains a title opportunity at Annihilation for the WAW Championship. (The exception being in 2007, when the match was not for a shot at the WAW Championship, but for the belt itself.
