4 rulings from Wizards of the Coast
- 6 June 2025The Hero token enters as a 1/1 creature, then the Equipment becomes attached to it. Abilities that trigger when a creature enters the battlefield see that a 1/1 creature entered the battlefield.
- 6 June 2025You may pay the Equipment's equip cost as normal to move it from the Hero token to another creature you control.
- 6 June 2025If the Hero token is destroyed, the Equipment stays on the battlefield.
- 6 June 2025If the job select ability causes two Hero tokens to be created (due to an effect such as that of Doubling Season), the Equipment becomes attached to only one of them.
