The dual-screen and stylus-based touch-screen elements provide a perfect basis for the dueling action, with players organising their decks using the stylus, with the monsters brought to vivid life in real-time reaction to the cards that are drawn. To this end, the bottom screen presents an uncluttered 2D view of the cards, with Nightmare Troubadour including recreations of over 1000 of the latest and greatest cards. As players organise their decks to block and counter attacks, so these battles are shown on the top screen in 3D sequences.
