One for All was a limited time game mode in League of Legends. Players battle in a 5v5 match in Summoner's Rift map similar to Classic mode, with the only difference being that all champions on each team are the same. This mode was first made available from 2013-11-22 to 2013-12-02.
One for All games can also be created and played as a Custom Game, and the map choice is not limited to Summoner's Rift; all other maps can be chosen.
Process
The process for selecting champions in One for All is called Vote Pick, which is somewhat alike to Draft Pick. A random player from each team will be chosen as the team captain and will take turn banning 6 champions (3 from each team) that all players have in the first step of this mode. After banning 6 champions, each player will have a chance to vote with their team and decide which champion will be played by the whole team. Players may pick any champion in their team's pool of champions (owned and free). If all players or the majority pick (3 votes) the same champion, then the whole team has to play as that champion. In the case that no champion won a clear majority, a random champion will be assigned from the pool of votes.

One for All: Mirror Mode
Last time you tangoed with One for All, you could nuke the enemy team with five Final Sparks or chain together a series of Unstoppable Forces. Some teams even achieved immortality with back-to-back-to-back-to-back-to-back Chronoshifts.
Now it’s time for One For All: Mirror Mode! We’ve moved the action to the Howling Abyss and changed the rules so players on both teams clash with the same champ. Soon you’ll really play pinball with Monsoons, dodgeball with Dark Spheres or hide-and-seek with ten times the Noxious Traps.
For this iteration of One For All, champ select is determined by the combined nominations of both teams. A vote tracker shows the nominated champions - if one champ achieves a strict majority, they’re chosen. If not, we base the choice on a weighted random from all the nominated champs, so if four people vote for Amumu, three people pick Blitzcrank and the last three all pick different champs; there’s a 40% chance everyone plays Amumu, a 30% chance everyone plays Blitz and a 10% chance for each of the remaining champs!
After playing your first game, you’ll permanently unlock the One For All icon (it’ll take a few days to hit your account). Additionally, we’ve added a feature to One For All: Mirror Mode that allows you to purchase a Battle Boost for your team during champ select. If you purchase one (150 RP), you’ll temporarily unlock all the chosen champ’s currently available skins for yourself and your allies. Everyone on your team also gets a one-game 100 IP boost!
This game mode was inspired by feedback from you guys, so let us know what you think! One For All: Mirror Mode will be live from May 29 through June 8 and we’ll be hanging out on the Community Beta looking for your thoughts and awesome ideas!
