If all players agree, you may begin the game
with Double Down in your command zone.
As long as Double Down is in the command
zone, whenever a player draws a card, they
draw two cards instead, whenever a player
gains life, they gain twice as much life
instead, and whenever a player taps a
permanent for mana, it produces twice as
much of that mana instead.
