Disciple of Blood Magic

Pay with Blood 1 (This creature enters the battlefield
with a +1/+1 counter on it. At the beginning of your upkeep, if there are one or more +1/+1 counters on this creature, you may remove a +1/+1 counter from this creature. If you don't, you lose 2 life.)
At the beginning of your end step, if you lost 3
or more life this turn, you may put +1/+1
counter on another target creature. Then each opponent loses life equal to the number of
counters on that creature.
