Flames of War

At the beginning of your upkeep, if possible,
choose an option that hasn't been chosen before:
-Discard your hand, then draw that many cards.
-Deal 3 damage to each player.
-Each creature your opponents control deals
damage to you equal to its power.
As long as all options have been chosen, Flames
of War gains "Instants and sorceries have
flashback equal to their mana cost".
