One of the most important aspects of any deck in Star Wars: Destiny is dice removal. Most dice removal cards come with a condition: giving your opponent a choice (e.g. Loth-Cat and Mouse (SR114)), requiring you to have dice in your pool (e.g. Guard (SR103)), forcing you to meet a play restriction (e.g. Defensive Position (AW104)), etc. Three things you should consider when deciding which dice removal cards to include in your deck are its play cost, playable situations, and place in the game.
Many of the best dice removal cards cost 1 resource to play: Electroshock (AW159), The Best Defense (AW75), and Isolation (AW85). With the upcoming release of Legacies this December, we have another 0-cost removal card that is worth a look — Crash Landing (LG137).
