Rulings
-
If the target of Kelsien's last ability dies before the ability resolves, you won't get an experience counter.
-
Each time Kelsien's last ability resolves, it creates a separate delayed triggered ability. If you untap Kelsien and activate its last ability multiple times in one turn, they'll each trigger when the appropriate creature or creatures die.
-
If Kelsien leaves the battlefield, you keep any experience counters you've received.
