Until end of turn, gain control of target creature and it gains haste. Untap and goad that creature. (Until your next turn, that creature attacks each combat if able and attacks a player other than you if able.)
The creature you gain control of must attack during your turn if able.
If, during a playerâ€™s declare attackers step, a creature that player controls thatâ€™s been goaded is tapped, is affected by a spell or ability that says it canâ€™t attack, or hasnâ€™t been under that playerâ€™s control continuously since the turn began (and doesnâ€™t have haste), then it doesnâ€™t attack. If thereâ€™s a cost associated with having a creature attack a player, its controller isnâ€™t forced to pay that cost, so it doesnâ€™t have to attack in that case either.
If the creature doesnâ€™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. It the creature canâ€™t attack any of those players but could otherwise attack, it must attack an opposing planeswalker (controlled by any opponent) or the player that goaded it.
If a creature you control has been goaded by multiple opponents, it must attack one of your opponents that hasnâ€™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, you choose which opponent it attacks.
Gaining control of a creature doesnâ€™t cause you to gain control of any Auras or Equipment attached to it.
Besmirch can target any creature, including one you already control or one thatâ€™s untapped.
Being goaded isnâ€™t an ability the creature has. Once itâ€™s been goaded, it must attack as detailed above even if it loses all abilities.
Attacking with a goaded creature doesnâ€™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.
