Massacre

Each opponent flips a coin. If it lands heads, the opponent chooses one creature and sacrifices
the rest. The opponent also loses life equal to the number of creatures sacrificed. If it lands tails,
you can either choose that you gain life equal to
the opponents life total divided by 4 (round
down), or gain control of 2 target creatures
from the opponents battlefield.
"Uh oh... here it comes.. HELP!"
