Prophecy is the final
Magic: The Gathering expansion set for the
Mercadian Masques block. It was released on June 5, 2000, with a total of 143 new cards.
Prophecy continues the game mechanics found in Mercadian Masques and Nemesis, along with introducting a new one, known as Rhystic Magic. A "rhystic" spell has multiple effects. After the first effect occurs, another effect will happen unless the opponent pays mana to prevent the effect. This is not really a totally new mechanic, just that there are quite a few cards that have this mechanic on the set, enough for them to highlight it.
Another set of key cards in the set are the "Avatars". Each color has an avatar, a 6/6 creature with a casting cost of 6 colorless mana and 2 colored mana. Each avatar has a condition that, upon being met, will reduce the casting cost to only the two colored mana.
