Final Volley

When you cast Final Volley, target a creature you
control. Tap all permanents on the field except
for the target creature. Target creature gets
+X/+X until end of turn. If X is greater than 5,
then Final Volley or target creature can't be the
target of spells or abilities your opponent
controls.
You lose the game at the beginning of your next
end step.
