Deadly Decision

Each opponent chooses 1 or more:
• Sacrifice a nontoken creature with the highest
power and a nontoken creature with the lowest
power, then draw 1 for each creature sacrificed
this way.
• Exert each mana source you control. Each
opponent gains 1 life and you surveil 1 for each
mana source you exerted this way.
• Set your life to 8 and your opponents to 20,
then sacrifice 3 nontoken creatures, then draw 3.
