Difficult Decision

Choose up to one-
•Destroy target permanent with converted mana
cost X.
•Exile target nonland, noncreature, nonartifact, nonenchantment, nonplaneswalker spell.
•Counter up to one third X spells.
{bull}All of the above. At the beginning of the next
end step, you lose the game.
If this spell would cause you to lose the game due
to a loss of life, you win the game instead.
