The battles of Warhammer: The Horus Heresy are rife with swift Reactions, mighty Warlords, and forbidden Psychic Powers. This handy deck of reference cards makes it easy to keep track of new rules and mechanics, so you can focus on your strategy. These cards will ensure you can take full advantage of the new Reaction system – they work as both a reminder to use them, and a rules reference for you and your opponent.
