Hey Charlotte, hope all’s well! Got an odd corner-case situation: can The Ozolith have both +1/+1 and -1/-1 counters on it at the same time? I know that if yes, once you move the counters to a creature, if the creature would still be alive, they’d annihilate, and I’m guessing that the same would be true if you animate The Ozolith. The only practical application I can think of is involving Thief of Blood. Thanks!
The state-based action that causes +1/+1 and -1/-1 counters on the same permanent to annihilate each other applies to all permanents and not just creatures. So, if your Ozolith gets both kinds of counters, either from a creature dying with both types of counter on it or from it already having one type and then getting the other type, it will lose an equal number of each of these counters until only one of the two types of counter remains. This happens before anyone gets priority so you'll never have the opportunity to move both types of counter onto the same permanent from the Ozolith.
