One ruling from Wizards of the Coast
- 23 July 2021If the Iron Golem can't attack or block for any reason (such as being tapped), then it doesn't attack or block. If there's a cost associated with having it attack or block, its controller isn't forced to pay that cost, so it doesn't have to attack or block in that case either.
