If Quina's HP is not 1, the ability will not work. It can't be reflected and works with Return Magic. A useful tactic in maximizing the spell's effect is to bestow Auto-Life on Quina and KO him/her so that s/he revives with 1 HP. Alternatively, Quina can use Matra Magic on him/herself. Limit Glove costs 10 MP to use.
