Split card

Split cards are Magic cards with two card faces. A split card is literally "split" into two separate cards each with its own card name, art, mana cost, text, etc. In any zone except the stack, a split card has two sets of characteristics; while it's on the stack, it only has the characteristics of the half being played. This provides many interesting interactions with cards that create effects based on converted mana cost. For example, if Dark Confidant reveals a split card, you would lose life equal to the total converted mana cost of both sides. However, Venerian Glimmer needs only be set to the smaller converted mana cost, not the combined converted mana cost.

They were introduced in the Invasion block, where each side was from a different color. In Dissension they were seen again, and each half was a multicolored card from a different guild; finally Planar Chaos introduced the first split cars where both sides were the same color (all split cards in PC were red).
