Theme / Keywords / Teammates
Lots of Suicide Squad teammates to chose from. If you need a little support and don't trust Deadshot's [12] attack value, you can hedge that bet with Fiddler from the Flash HeroClix:



Remember though, you need some brawling tanks to keep them distracted while Deadshot does his business. From Trinity War, and nice cheap option would be Copperhead to keep them busy:



Cost
At 100 points it's tough to not like Deadshot, especially considering his Ranged versatility.

On a 300 Point Team
He's just perfect on a 300 point team, with lots of friendly options for teammates. You've got plenty of room for a tentpole figure or a balanced team.

On a  400+ Point Team
Still excellent, but I'd argue that he's less useful at 400+ point games. You'd really need to push him and be ready to move him around due to all high point figures you'll see.

Final Rating:  A+

Perfect at 100 points - he's got a [12] attack on the first click with a potential range of 12 (or 13 if you can get perplex in there).

Edit: Note that Deadshot can hold his own very well in melee too. Why? Because he's a sharpshooter, which lets him use his Ranged Combat Expert against adjacent opponents (or Energy Explosion if you're feeling crazy). And as I mentioned, Precision Strike is a good insurance late in the dial too.
