The entire deck is built around one card, Ret-time Reviver Emit-ter. The deck uses Ret-time's powerful effect to control the board state and uses xyz monsters to overlay on top of Ret-time to reset the banish. In addition, the deck uses some powerful trap engines like Paleozoic and Phantom Knights to also help control the board state further.
In total, the deck is pretty good for its price at slowing down the game and manipulating the board state in your favor. The deck isn't the most consistent but it gives an enjoyable playing experience if you enjoy control decks.
