I'm buying everything single carded. So far, I have Superman, Batman, Wonder Woman, Aquaman, Flash, Cyborg, Darkseid, and only one Parademon (I consider him an army builder). I'm still missing Hal Jordan of the figures released in 2012.
Of the ones appearing this year, I'm still no decided completely about Green Arrow and Simon Baz, but I'll be getting Martian Manhunter, Swampthing, Joker, Black Manta, Deathstroke, and Black Adam for sure. I'll pass on Captain Cold (I never liked Flash's rogues gallery that much, except for Vandal Sagave, Zoom, and Grodd), and Pandora looks interesting, too.
The one thing I'm a little disappointed for is that Catwoman will only come in the next 7-pack, but I'm hopeful that they'll release her single carded in the near future, just like they did with Superman. Same with Katanna and Vibe, but I'm not so crazy for them.
