Released in IACP S5, Cassian is another figure that often gets classified as a hybrid offense/support figure. His Strike Team ability allows him and another figure to get a headstart out of the deployment zone, and then up to 4 figures that are outside the deployment zone before the round start get a damage power token. This synergizes well with figures like Hera Syndulla and the Rebel Pathfinders. He also has great synergy with his friend K-2SO since he turns on K2's ranged attack option by providing him the 2nd power token he needs. They're also both Spies which contributes to a list's spy count for Comm Disruption.
As a Spy/Leader, Cassian's offensive command card options are fairly limited, but his unique Command card Sniper Configuration can really boost his attack power for a single attack, as well as letting him attack a figure he might otherwise not be able to. We imagined this in design as him taking a high position on the map above line of sight blocking obstacles by having another friendly figure spot the target for him.
Finally, Cassian's "It Will Be Alright" ability to sacrifice another friendly figure might look like flavor text to tie this card to Cassian's introductory scene in Rogue One, especially with how steep the cost is to use it, but there are ways to make the cost of defeating a friendly figure work for you. The big one is with Chewbacca, using It Will Be Alright to sacrifice a cheap figure like an Alliance Smuggler, getting a bonus attack with Cassian but also reactivating Chewbacca with Debts Repaid. You can also sacrifice companions to the ability, meaning you could sacrifice something like Jarrod's J4X companion to trigger the ability, or if you pay a premium for Saska or Temporary Alliance in a Scum list, you could bring an Ugnaught Tinkerer to feed Junk Droids to Cassian's ability. Keep in mind though that you can't sacrifice a figure that can't be defeated, like Maul, and if you defeat a figure with It Will Be Alright, that figure can't be saved by something like Second Chance or Miracle Worker.
