For those who don't know, DuelingBook.com added a create-a-card feature with its own room to go with it. This has pretty quickly spawned an idea for a new format...
Meme Format Rules
1. All cards in your deck must be custom cards.
2. Games are played best out of 1, no sidedecking.
3. You need at least 5 people watching your duel in order to start (the more, the better).
4. The game ends when a player's lifepoints are reduced to 0 or another win condition is reached.
5. However, when a win condition has been reached, it's not necessarily the case that the player who won actually wins. Instead, the watchers of the duel vote on whose cards were funnier/more interesting/more creative. The player who got the most votes actually wins.
Basically, think of it as a hybrid between Cards Against Humanity and Yugioh.
