Can only be cast if "Touma Kamijou(pre-memory
lost)" and "Index Librorum Prohibitorum" are

Kamijou(pre-memory lost)" from the battlefield
and search for "Touma Kamijou (memory lost)"
in your library or graveyard and put it in your
hand. Tap "Index Librorum Prohibitorum" and
remains tapped until your fourth upkeep. Shuffle
your deck when you are done
