Dregn didn't get banned because he never appeared on the format election page. If he did, he'd get a ban. I think the same way of Tsubame. She won't appear there in the near future, though, because she's new and not many people have her yet.
I find her better than Dregn. Her damage isn't crippled by SoA, she doesn't need the bonus (so is better in halves). C Wing doesn't matter at all, you can use her in a halfdeck with any defeat: - life and she can ko with all of them (even Embolt). Plus, she has Chan on her clan, a 10 power card that 2hkos with her. Dregn doesn't have that.
Shes not Gonna Get a BAN. Why? Because......
2. SOA will always be a there NO MATTER WHAT. Ban Noodile Jeena Arno Yokie Rico and Roots players will bounce and find something to play with, trust me. GHIEST is a crowd fave.
3. 7 Power as a main nuker is low for me esp. if you have no power and attk manip to start with. So yes maybe as 4star she may be nice but as main man? I dont really know.
Yes but Dregn is weak against SoA. I don't have much experience with the Vortex bonus but it seems to be pretty useful(especially for cards like this). Though SoA also stops a nice perk for this card, it doesn't kill it as much as it kills Dregn so this card is more solid/powerful than Dregn simply because of still being solid in the face of SoA. I agree it shud be banned.
