I CAN ONLY GET A COUPLE WAVE 4 .. Who Should I Get??

Well I have been put on a skylander budget and told a maximum of two Wave 4 characters (for now). I am heading to Toys r Us tomorrow. I also posted a youtube video asking the same question. I have a good idea of who, but there is starting to be a theme in my youtube comment section. Blackout has popped up much more than I expected. So while a light/dark character will most likely be one I was leaning towards spotlight. If you have wave 4 let me know which characters you like and are enjoying in the game
Thanks
