assuming you already have a working simple "pvp stone", you can do it with just a few things:

1) many arenas
2) a central area with many "squares", each one with 1 stone/gate/whatever to enter on each arena. You must place them in a championship order: 16 (start) -> 8 -> 4 -> 2 -> 1 (winner)
3) on the end of each round, send the winner to the next "square" and take the loser out of the event

this will let all battles flow automatically. Just send all players to the correct start "square". Winners will keep advancing to next square, and the last player remaining on the last square will be the champion
