The Thing

X: Exile target creature with toughness value
X and put a thing counter on it. The Thing
becomes a copy of that creature, except
it has this ability. At the beginning of your
end step, you lose life equal to the number of
creature cards with thing counters on them.
At the beginning of your upkeep, if there are 7
or more creature cards exiled with thing counters,
you may draw that many cards, and if you do,
you lose the game at the beginning of your next
end step.
