One ruling from Wizards of the Coast
- 2 February 2024Activating Commander Mustard's last ability multiple times will cause Soldiers you control to gain multiple instances of the triggered ability. For example, if you activate Commander Mustard's last ability twice and then attack with Commander Mustard, it will have two instances of the triggered ability. Both will trigger, and the defending player will take 2 damage.
