In a Powered Cube game, I cast Fractured Identity, targeting my opponent's Glorybringer, which resolved and created a Glorybringer token on my battlefield. I then moved to combat and attacked with the token, but I did not receive an opportunity to use Glorybringer's ability. My opponent controlled a Boo token created by Minsc & Boo, which is a non-dragon creature, so I should have been able to use Glorybringer's triggered ability to deal 4 damage to the token. However, the ability did not trigger, so I was unable to kill their token, causing me to lose the game when it attacked me on the following turn.
