Stat cards are a tremendous benefit to the game of warmachine and hordes, allowing quick reference to the entire suite of your models’ rules and abilities, as well as providing a place to track damage done to multi-wound models. They’re definitely an invaluable resource to the game, but as expansion books are published, each faction gets access to more and more models and units. For the player that means more and more cards in their collection to keep track of.
When I first started playing, most locals sleeved their cards individucally and kept them in a deck box. I quickly adopted this method and found a couple products that I really liked – Dragon Shield card sleeves and Ultra Pro deck boxes. I’ve used this set up for years – it’s quick and dirty but it works. I never had any problems at all in actual play, but as my army collections started getting bigger, keeping the cards sorted became harder – I started chucking whatever I had played back in the box after each game. Searching for cards when building armies on the fly started taking longer and longer, so I started looking at alternatives.
