Ditto match
From SmashWiki, the Super Smash Bros. wiki
A Ditto Match is a match where both players choose the same character. They are different from other matches in that neither player has a match-up or stage advantage over the other player. The name comes from the definition of 'ditto', which means 'the same'. Ditto matches occur at times during tournaments.
[edit] Strategies
Strategies for a ditto match often varies greatly from the character's normal strategy. This is especially the case for characters such as Marth or Jigglypuff, whose strategies rely on an advantage in range, mobility, or attack speed. This variation is removed during a ditto match.
