Quest for Pure Flame

If you activate the second ability of more than one Quest for Pure Flame in the same turn, the effects are cumulative. Two such effects will cause damage from sources you control to be multiplied by four; three such effects will cause damage from sources you control to be multiplied by eight.

The second ability affects all sources you control that would deal damage to a permanent or player at any point in the rest of the turn.

If multiple effects modify how damage will be dealt, the player who would be dealt damage or the controller of the creature that would be dealt damage chooses the order to apply the effects. For example, Mending Hands says, “Prevent the next 4 damage that would be dealt to any target.” Suppose a spell controlled by a player who has activated Quest for Pure Fire’s second ability would deal 5 damage to a player who has cast Mending Hands targeting themselves. The player who would be dealt damage can either (a) prevent 4 damage first and then let Quest for Pure Fire’s effect double the remaining 1 damage, taking 2 damage, or (b) double the damage to 10 and then prevent 4 damage, taking 6 damage.
