Travel through the Multiverse

Move a creature of your choice to the owner's
hand, and flip a coin. If heads, give yourself
five life and all opponents lose 5 life. If tails,
all opponents gain 5 life and you lose 5 life.
"The universe is a dangerous thing; let alone
the multiverse. You may find yourself in a
dimension with no life, or worse, nothing
at all." — A Guide to the Multiverse
