True Aurora

This rule affects one player, who must have two
decks. Each deck must have The Great Aurora
in it and be able to play it.
• Each deck must have all basic lands and at least
50% of other cards from the Lorwyn and
Shadowmoor sets respectively.
• Before beginning of the game, a coin flip
determines which deck is to be used.
• When The Great Aura resolves, the player who
casts it switches to the other deck before drawing
cards.
