Fantasy Doppelganger

When as the owner of multiple fantasy teams, you play against a team in one league that is almost identical to your own team in another league. Fantasy Doppelganger phenomena is generally seen as a harbinger of a bad fantasy weekend, as rooting for your own team in one league means you are rooting against yourself in another. Feelings of euphoria are quickly replaced by general malaise as success in one league leads to failure in another.
