Card of the week

Card of the week is a brief thing that happens before every episode in the Yu-Gi-Oh! 5D's Dark Signers (arc). There are 5 cards, and after the 5 are shown, one of them is picked by Leo and Luna, and they will briefly talk about it. Before the 5 cards turn over to be shown, the twins say "What could it be? What could it be? This is what we have this week!"
