Last Man Standing

creatures you control get +2/+2, creatures
your opponents control get -1/-1.
If a creature you control dies, exile it, other
creatures you control get +X/+X,
where X is the exiled creatures toughness.
If you control only one or less creatures,
create a 0/0 army and distribute ten
+1/+1 counters among any number of
target creatures.
