The Twenty-third card is Hey, Trunade!, which is a spell that returns all set spells and traps to the hand. It is a lesser version of the card Giant Trunade that does the same thing without needing the cards to be face-down. It can be useful against Paleozoic decks or anything else with a lot of traps. It can be more useful than the Giant Trunade if you run continuous or equip spells and traps, but if not then you would be better off using the other one. A decent card, and thank you to Konami and Hill and Knowlton Strategies for giving us this Advent Calendar.
