It happen to me during previous event before. First event, I want gandora so much but that is the only card I fail to get. Later I want gamma but result is same. I even got a valkyrion and gandora 3 copies. Latest is ishzark. This time, I didn't set what card I want and just satisfy with what I got. And suddenly, I got 3 copies for each card. This RNG really know how to play with us.
This is so annoying! I can feel your pain bro! When we want to get a card, all cards drop except that card. In this event, it was like OK to me not to get all cards, however, I got more than 3 copies of each one. In the last Muto's event, which was my 2nd one, I wanted so badly to get at least one copy of "Union Attack," and the result was that I got all Muto's cards except that one!

Not your stage level. but the character itself. Plus, max level for character is 35 only. So I think, you get it wrong. Check paradox brother level and you can see after you level it up to level 10, you got labyrinth, the other one after level 33
In other word, what I mean is use paradox brother as your character and level it up. You will get labyrinth as level reward on level 10 and level 33. So do not worry even you can get it through this event. Just level up paradox bros and labyrinth will be yours.. =)
