Hei Bai, Spirit of Balance

Hei Bai's last ability doesn't cause you to move counters from Hei Bai onto the target creature. Rather, you put the same number of each kind of counter Hei Bai had when he left the battlefield onto the target creature.

Hei Bai's last ability puts all counters that were on Hei Bai onto the target creature, not just his +1/+1 counters.

If Hei Bai has -1/-1 counters on him when he leaves the battlefield, that ability will include those as well. This may result in the recipient of the counters dying.
