As Kushieda already mentioned, it's best to use them on good premium cards. Because it can be difficult or costly to get a second copy of summon only cards. I once pulled a UR point booster that was a salvo with a couple of thousand jewels and used a mirror that I had been saving on it; it got me to R13 at the end of that event and likely cost a lot less than if I attempted to summon a second copy.

@Blaze: That happened when I used a mirror on Tide a while back. I think it's that the amalgamated mirror has higher atk and def stats than some UR cards.
