When an opponent's monster declares an attack, if you control an "Altergeist" card: You can Special Summon this card from your hand, and if you do, negate that attack. If this card is Special Summoned: You can target 1 face-up card your opponent controls; negate the effects of that card while it and this monster are face-up on the field.
