Red Death, Shipwrecker

Being 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.

If the target creature is an illegal target as Red Death’s ability tries to resolve, it won’t resolve and none of its effects happen. You won’t add any mana, and the creature’s controller won’t draw a card.

If, 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.
