7 rulings from Wizards of the Coast
- 17 April 2020Only one creature is required to block the enchanted creature. Other creatures may also block it and are free to block other creatures or not block at all.
- 17 April 2020If each creature the defending player controls can't block for any reason (such as being tapped), then the enchanted creature isn't blocked. If there's a cost associated with blocking the enchanted creature, the defending player isn't forced to pay that cost, so it doesn't have to be blocked in that case either.
- 30 June 2023If a creature you control has been goaded by multiple opponents, it must attack one of your opponents that hasn't goaded it, as that fulfills the maximum number of goad requirements. If a creature you control has been goaded by each of your opponents, the creature must attack an opponent (rather than a planeswalker or battle), but you choose which opponent it attacks.
- 30 June 2023If the creature doesn't meet any of the above exceptions and can attack, it must attack a player other than the controller of the spell or ability that goaded it if able. If the creature can't attack any of those players but could otherwise attack, it must attack a planeswalker an opponent controls, a battle an opponent controls, or a player who goaded it.
- 30 June 2023Attacking with a goaded creature doesn't cause it to stop being goaded. If there is an additional combat phase that turn, or if another player gains control of it before it stops being goaded, it must attack again if able.
- 30 June 2023If, during a player's declare attackers step, a creature that player controls that's been goaded is tapped, is affected by a spell or ability that says it can't attack, or hasn't been under that player's control continuously since the turn began (and doesn't have haste), then it doesn't attack. If there's a cost associated with having a creature attack a player, its controller isn't forced to pay that cost, so it doesn't have to attack that player.
- 30 June 2023Being goaded isn't an ability the creature has. Once it's been goaded, it must attack as detailed above even if it loses all abilities.
