I have been saving for a brick. Which set is most playable, Batman, Amazing Spider-Man, or should I wait for the Teen Titans set?

I'd say ASM is the way to go. There are more playable pieces in that set, and the Super Rares seem typically better than those in Batman. One thing though is that the Batman Chases seem generally better (and you have both GL Bats and Caped Crusader which are like striking gold.)

Idk. Batman's alright, but I think ASM will give you more to work with if your collection is small.

yea asm and you can always trade your extra for batman stuff i would try to get big barda and other good ones from batman

ASM has best CUR and SRs aren't bad, Batman is not good, Teen Titans will suck. I think that ASM will be the way to go. Pieces are great and your guaranteed a chase or Prime and primes are all good I do not like the Chases though. You should def get ASM.

Not guaranteed a chase in ASM. Or Batman.

Will say ASM has pieces that are more fun to play. But if you strike it big in batman. You hit it big. Freeze, GL Bats, Prime Bat, Prime Bruce, cop cars, the bug, insider.
It's not a bad set. If you are looking for a financially safer decision, go asm though.
I bought a batman brick and got Selina Kyle prime, cop/tank, doc Phos, Rex Mason, and booster gold. Fail. Lol

Most playable is definitely ASM. I bought a case and wasn't unhappy with any of my boosters.
