Albedo, Soul Eater Mistress

When Albedo enters the battlefield you may put
X -1/-1 counters on target creature you control,
if that creature doesn't die, put the same number of +1/+1 counters on Albedo.
Whenever Albedo attacks, target creature gets
-X/-X where X is half the number of -1/-1
counters on creatures you control rounded down.
Be satisfied that your trash stained soul still had some
usefulness to The Great Nazarick Tomb.
