2 rulings from Wizards of the Coast
- 23 June 2020If you create a Beast token, that token can't attack or block during the same combat, even if it gains haste.
- 23 June 2020Players can cast spells after Elder Gargaroth's triggered ability has resolved but before blockers are declared (if it's attacking) or before combat damage is dealt (if it's blocking).
