12 Labors

Whenever a creature an opponent controls dies, if it had a power or toughness of 6 or greater you get a Labor counter, At the beginning of your upkeep you may gain life equal to twice the amount of Labor counters you have or deal damage equal to the amount of labor counters you have to target creature an opponent controls. You may only have up to 12 Labor counters. If you would get a 13th Labor counter instead draw a card.
