Flipping a coin

Flipping a coin is a method of randomization of effects with two possible outcomes of equal likelihood.

The coin flip was introduced as a mechanic in Arabian Nights with Mijae Djinn, Ydwen Efreet and  Bottle of Suleiman. Any color can flip coins, but red does it most. It also appears on artifacts. If the card is multicolored, so far it always has been part red. There is one blue card with the mechanic (Zndrsplt. Eye of Wisdom), one black card (Tavern Swindler) and one green Un-card (Flock of Rabid Sheep).
