Maaaaaaaybe if more of my unevo'd shit were leveled, like, at all.
Though I do have a D/D Batman at least. I actually own a lot of the relevant monsters for potential teams. :V
After scoring a Batman-arang myself, I guess I've probably got a pretty ok dark team for being a non-IAP player...Got that, got the heartbreaker, the orb changer...I'd just need some recovery or something, plus my team needs leveled badly if I'm to even look at something like that. Hm. Probably still way out of my league, but it's definitely closer to being in my range than most!
EDIT: Nevermind, I didn't notice its stamina cost..Took a look at its encounters, too...Uh no. Kinda annoying, but I guess it can't be helped.
