The effect of "Rainbow Veil" starts being applied when the attack is declared. It does not start a Chain. It does not target the opponent's monster.
Effects that activate in the GY or removed zone will not be negated by "Rainbow Veil".
If a monster affected by "Rainbow Veil" is not destroyed by the battle, its effects remain negated for the remainder of the Battle Phase.
When "Rainbow Veil" is removed from the field or negated, the effects of the monster you battled with are no longer negated.
If a monster equipped with "Rainbow Veil" attacks a face-down monster, when that monster is flipped face-up in the Damage Step its effects are negated.
If a monster affected by "Rainbow Veil" is flipped face-down after the battle, its effects are no longer negated.
While "Rainbow Veil" is equipped to a monster that is unaffected by the effects of Spell Cards, the effect of "Rainbow Veil" is still applied.
