Linda, the Leech Queen

Linda, the Leech Queen enters the battlefield
with four +1/+1 counters on her.
Whenever you lose life, put that many +1/+1
counters on Linda, the Leech Queen.
At the end step of each of your turns, remove
half the +1/+1 counters on Linda, the Leech
Queen from her, rounded up, and create a
number of 1/1 black Leech token creatures
with Lifelink equal to the result.
