LOL Limz you shouldn't drink and type!
But Sideboard like MTG is an interesting idea indeed. I was thinking best 2 out of 3 for a tournament setting. If you lose your previous match you get the chance to swap out your entire party before the next match. A limited swap like a sideboard should encourage more well-rounded party setup though.
I honestly just felt like being silly.
Marvel vs Capcom 3, you see the enemy team composition and you can switch up the load order in the middle of the loading screen.
Magic the Gathering only allows you to sideboard after the first match and it's a 2 out of 3.
2 out of 3 would be ideal as would having side board/limited change options.
Generally, tournament formats smooth out of everything and have restrictions such as bans and picks to limitations (1 of each, no dupes).
