The card she's holding up is Wise Core, so she's probably running anime!Meklord cards -- meaning her field being full is probably to do with how Wise Core fills your monster card zones with all the pieces of Wisel when it (the Wise Core) is destroyed by a card effect. (Meklords were made of various monsters as components in the anime, y'see.)
As to why she's still holding Wise Core rather than sending it to the Graveyard, I blame dramatics.
