Name - You *won* the game
Duration - 1 month
Legendary
Turns cost - 1
Target - oneself only
Effect - The Player won the game. He/she is the winner (for a whole month) and a special achievement saying "winner of the game" will compare on his/her achievement page for a month.
Every other player will have to send 1 shiny gold coin to the winner of the game as a form of respect and accepting the fact that somebody actually won the game. The winner's name will be mentioned in the Avonmora Herald and in every newspaper.
If another player (or even the same caster) would like to cast the same voodoo, he/she has to wait a month.
Just joking. I see many suggestions and I wanted to do my part
