A topdeck is a term for a card that can be played immediately when drawn, even if the user has no other cards in their hand or on their side of the field. Drawing such a card during the user's Draw Phase (from the top of their Main Deck, hence the term's name), usually when the user is at an overwhelming disadvantage, is referred to as top-Decking or topdecking. The word "topdeck" may also refers to "The top card of the deck".
