Baby New Year

Flash, Vigilance
At the beginning of each end step, put a +1/+1 counter on Baby New Year.
Whenever you put a +1/+1 counter on Baby
New Year, if it has more +1/+1 counters on it
than the number of opponents you have, remove
all +1/+1 counters from it.
"Cheers to a new year and another chance for us to get it right." -Oprah Winfrey
