Increasing the number of cards in your hand gives you more options from which to choose. Many cards in this category add other special abilities, making this category very versatile. For example, several “draw” cards add the ability to interrupt the battle and play the next card (e.g., Words of Encouragement and Swift Horses). The battle is interrupted while the remaining special abilities on that card are being carried out. Cards drawn in these circumstances are valid to play if you choose to play the next card. Cards drawn in this manner can be negated (see Negating Special Abilities in the rulebook [15]).
Cards that decrease the number of cards in a player’s hand are described in Discard or Remove.
