Graft Surgeon

In some unusual cases, you may end up putting the appropriate counters on more than one permanent. For example, if you control The Ozolith (a card from the Ikoria: Lair of Behemoths set) when Graft Surgeon dies, you'll put the appropriate number of each kind of counter onto both The Ozolith and the target creature.

Graft Surgeon's second ability doesn't cause you to move counters from Graft Surgeon onto the target creature. Rather, you put the same number of each kind of counter Graft Surgeon had when it died onto the target creature.

If Graft Surgeon has -1/-1 counters on it when it dies, that ability will include those as well. This may result in the recipient of the counters dying.
