I don't see what is so great about the Lithograph. Anyone who plays their deck knows what is in the prizes when they use some form of search card and cycle through their deck. Sure it combos well with RR Rotom but you can't search out the lithograph. Normally the only time you would use Azelf is when you need something crucial on the fly that you know is prized but Lithograph + Rotom requires both of them in hand to work. When Azelf is gone im sure it will be a decent replacement though.
The twins are most likely going to be a staple in every deck it is the only card I really like in this expansion.
