Vergil is going to be the king of the safe DHC thanks to Spiral Swords. This is something that distinguishes him from Dante, since Dante’s only safe DHC is Devil Trigger, and if he’s offscreen with DT active, you can’t bring him back in safely. With Vergil, you can run him on point, then DT and DHC to a safe hyper to take advantage of buffed assists. Then if you need to bring him back for whatever reason, you still have Spiral Swords to DHC into for bringing him back onto the screen safely.
Also, characters with screen covering hypers that don’t disappear on DHC and don’t hit immediately will allow Vergil to do some dirty stuff by doing DT or Spiral Swords afterwards and then teleporting for an instant mixup. Dante can do kinda the same thing, but the mixup aspect of it is slightly more one dimensional thanks to him having only one teleport, while Vergil has three to choose from.
For fun, trying to figure out the best configuration for Team DMC. I’ve had several ideas, but some of them seem like they’d be pretty impractical from a meter basis.
