It's basically a crew battle except 1 on 1. (Credit to Overswarm for the initial idea. I've only tweaked it slightly.)
-Both players pick 5 characters each. They must all be DIFFERENT characters. Each character gets 3 stocks, so a total of 15. (I was thinking 4 stocks, but then people would just hog TV's and it would take too long.)
-Both players will secretly pick their opening character and must use them first upon the start of the match. Random neutral stage unless a stage is agreed upon. All legal counterpick levels are allowed. (-Dependant on whatever tourney you are at)
-When a player loses all of a character's stock, they will pick a new character from their list and counterpick stage. The winner keeps his remaining stock from the previous match, and must stay that character for the next match.
-This occurs until a player loses all remaining stock, and loses the match, shamed and humiliated for eternity.
The more diverse player is definitely favored in these matches, and strategy definitely comes into play. Do I see an Ironman tournament in the near future......................? Let me know what you think.
