If, during your declare attackers step, Manticore Eternal is tapped or is affected by a spell or ability that says it canâ€™t attack, then it doesnâ€™t attack. If thereâ€™s a cost associated with having it attack, you arenâ€™t forced to pay that cost, so it doesnâ€™t have to attack in that case either.
If multiple creatures block a creature with afflict, afflict triggers only once.
If a creature is attacking a planeswalker, that planeswalkerâ€™s controller is the defending player.
Afflict resolves before combat damage is dealt. If this loss of life brings a player to 0 life or less, that player loses the game immediately. A blocking creature with lifelink wonâ€™t deal combat damage in time to save that player.
Afflict causes the defending player to lose life; itâ€™s not damage or combat damage.
