Goblin Poisonmaster

When Goblin Poisonmaster enters, put a +1/+1 counter on a Goblin you control. Then, target creature gains X -1/-1 counters, where X is the highest amount of +1/+1 counters on a creature
you control.

When Goblin Poisonmaster dies, you may remove
two +1/+1 counters from target creature an opponent controls.
