Something I have noticed while testing Manual Battles:
Cards like Antique Armor Fossil (and other fossils, Unidentified Fossil for example) as well as cards like Lillie's Poké Doll cannot be put onto the bench from hand. Likewise, Snorlax Doll cannot be put into the active from starting hand. I am playing a fighting fossils GLC deck, so it's pretty important to the deck as a whole. Also, if we're talking about standard, cards like Bastiodon are seeing play, so this problem is relevent to people testing and playing standard decks.
