Mirror Universe

{t}: Sacrifice Mirror Universe during your
upkeep and trade your number of life points
with opponent. For example, if you had 2 life
points and your opponent had 10, you would
now have 10 life points and your opponent
would have 2.
Effects that prevent or redirect damage may
not be used to counter this change of life.

Make new friends, but keep the old. One in silver
and the other's gold. - Bender
