Thanks @ducecrypto. I edited the Terms. I kept "player" instead of "Battle Mage/Summoner".
Yes, having a single-elim would be fun too.
I was more thinking of an ESPORTS style - but I do agree that the Time sink is a big down side. I was calculating how long a match would take & that it would be difficult to work with large batches of players (which I'd like a large mob to somehow get involved) or broken down into different Small Scale Skirmishes to climax with an End of Year battle between the "last 4 (or 6) Kings" to determine the Year's King!
But whatever game-mode we end up with - I want it to be a spectacle!
I totally agree with the need for a spectacle event to get attention to our game. Great ideas!
