The listing, mtg cards (unglued) has ended.
Chaos confetti- Tear Chaos Confetti into pieces. Throw the pieces onto the playing area from a distance of at least five feet. Destroy each card in play that a piece touches. Remove the pieces from the game afterwards.
Free-For-All- When Free-for-All comes into play, set aside all creatures in play, face down.
During each player's upkeep, that player chooses a creature card at random from those set aside in this way and puts that creature into play under his or her control.
If Free-for-All leaves play, put each creature still set aside this way into its owner's graveyard.
Common Courtesy- Counter any spell unless its caster asks your permission to play that spell. If you refuse permission, Sacrifice Common Courtesy and counter the spell.
I dont think these are legal to play in duels but my friends and i use the unglued card all the time to make it more interesting.
