Ok not sure if I created these correctly as its been so long since I bought or played Magic but here goes nothing. Hope everyone likes .
The Trilogy War
10 Colorless, 2 Black, 2 Red
Trilogy War can only be countered by Prodigal Sorcerer. Deck may contain only 1 Trilogy War Card.
When Trilogy War comes into play, all untapped creatures, artifact creatures etc able to attack must do so. At end of players turn destroy all cards in play on all sides including lands, artifacts, and any surviving creatures, both tapped and untapped, leaving only un-drawn cards in play. Trilogy War is also destroyed.
If any opponent controls a Prodigal Sorcerer, may tap it to prevent Trilogy War from being played.
Deck may contain only 1 Trilogy Master Card. Can be tapped to counter playing of Prodigal Sorcerer.
If Trilogy Master is in play when Trilogy War is played, Tap Master to avoid total in play card destruction for owners side, return Trilogy War to owners deck. Shuffle deck. All other sides still lose all in play cards on table.
