New tournament idea

There should be a new tournament format that forces the pros to use all the champs available. After each game the champs that were used in the previous game are no longer available to use for the rest of the tournament. The tournament ends once all the champs have been used and of course the best team wins. If there is an odd number of champs to even it out Riot could allow a champ save option to revive a champ or they could just introduce a new champ or two throughout the tourney to bring the champ pool to the correct amount. I believe this could be a very fan friendly experience as I know a lot of fans would love to see the pros using some of their favorite champs that are just never used in a pro structure. I also believe this could be fun for the pros as they will have to be more careful with their picks, so they won't run short on their champ pool in the later rounds and leave themselves short on good picks.
