Well, Zatanna is capable of reality warping feats with prep.
On the other hand we have Wonder Woman with prep which is always crazy and freaking Circe. Circe > Zatanna by far.
Team lantern is a bit incapable IMO, and unless we're letting the Flash team use time travel than I don't see them taking many wins against S Shield, Team Wonder, or Team Mind.
Team Mind has crazy prep guys, so they're the wildcard, but I'm not sure if technology and smarts is up to snuff with the magical capabilities of S Shield and Wonder.
I'd give the majority to team Wonder because they're just stacked.
Circe > Zatanna by far? Not so sure id say that. Zatanna has paralyzed Circe in the past. Shes also conjured up Herbs to protect her as well as others from Circes magic.
Hmm, any of these teams could take wins versus all of the others. Because of the prep, I think Team Lantern and Team Flash might not be able to take enough wins. I think overall Team Wonder has the advantage due to their abundance of magic. Team S Shield is a very close second due to Zatanna and depending on her, she could tip the scales in their favor.
It comes down to the 2 of them, but I think that while Circe and Zatanna are battling it out, I think the rest of Team Wonder could take out Team S Shield.
Circe has skyfather level feats though. Zatanna doesn't really have much in comparison aside from the Starbreaker thing and the reality manipulation, which isn't really cannon because Seven Soldiers isn't in continuity.
She's got "supposed" amazing prep because of her house and equipment, but she doesn't really have that much PROOF that she can bring shit to the table.
