I have some more ideas for gimmick matches that the WWE could use, because I'm a stickler for gimmick matches.
Steel Escape match: Its a steel cage within a hell in a cell. the insides of the cage as well as the cell are lined with weapons. The first superstar who climbs out of the cage and opens the cell door wins(I know this sounds similar to the kennel from hell match, but there are no dogs involved and this match has four participants.)
I don't have a name for this next match, but the concept is that its a tag match were one partner from each team is locked in a cage at ringside. The first superstar to score a pin-fall or submission has their partner freed and the match becomes a 2 on 1 handicap match.
Flaming Casket Match: I've seen videos of this match from Japan. It's basically a regular casket match, except after someone has shut their opponent in the casket, they then set the casket on fire.
