Scolding Administrator

Scolding Administrator's last ability puts all counters that were on Scolding Administrator onto the target creature, not just its +1/+1 counters.

It doesn't matter if the creature or creatures targeted by the spell that caused the repartee ability to trigger leave the battlefield or stop being creatures before that spell resolves. As long as that spell targeted one or more creatures when it was cast, the repartee ability will trigger and later resolve.

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 Scolding Administrator dies, you'll put the appropriate number of each kind of counter onto both The Ozolith and the target creature.
