Just clarifying: one thing for you to keep in mind is that the Xion card is a reward for daily Lux victory (that is to say, having more Lux count than the opposing team at the end of the day), not defeating the subspecies bosses in itself.
And yes... basically what Tigerruss said. To be eligible for the rewards, you will need to have beaten a subspecies whose level is 30 or higher. As far as I'm aware, if you hadn't beaten a L30+ sub yet, you won't get the prizes even if your team had more Lux than your opponent.
