Born from Magic the Gathering, the Deck Building mechanism sees you adding cards (usually) to an individual deck of cards to improve your deck as you cycle through it. Deck Building can also include throwing bits and pieces into a bag and drawing them blindly on your turn. The same concept, different implementation. All of the games below have some level of Deck Building in them, even if it is not the core mechanism of the game. Don't worry; we won't put any lame references to pressure treated lumber in this description.
