One ruling from Wizards of the Coast
- 29 April 2022If Call In a Professional deals damage to a creature with a shield counter on it, that damage will not be prevented, but a shield counter will still be removed. If that damage is enough to be lethal damage, the creature will be destroyed, even if it still has more shield counters on it.
