Best user of Cloud maiougi?

Tbh you should probably just pick your favorite you'll merge if he's going to be a dragon check in arena. EDIT Maybe Kaze. I think a Close Counter Vantage QR Kaze is too good and funny to pass up. Also he's cute

I actually advocated for it on +atk Jakob. It doesn't take a lot of spd to double most dragons, so he can just go with neutral spd and swift sparrow (or if for some reason you WANT to burn a death blow 4, use +spd and get a spd buff if he needs it). His mixed bulk is surprisingly good against adaptive damage, and he can keep topping it up using renewal + flashing blade sol because most manaketes have atk in the 40s due to lightning breath's low mt and their atk stats not being all that high to begin with. It's kind of a counterintuitive and maybe unorthodox idea, but I'd like to test whether it works.

The other idea I came up with is windsweep Kagero with phantom spd. The idea is that dragons get OHKO'd while anything else that's not a mage won't be able to hit back, so she will get a free hit and a debuff on the whole enemy team.

I don't recommend this weapon for a unit like Kaze with very lopsided defenses. His def is clearly meant to be barely able to take him through one hit; it's not going to work when he can't use desperation.

Sothe is probably the best choice. If you max out his Atk, you can just one-shot dragons by having over 100 Atk against them.

Sothe or Kagero are great general choices since their naturally high Attack allows them to make great use of the effective scaling. However, going off of the most commonly used dragons, a Red Dagger user would be a great choice, but they don't exist yet so HF!Elincia and Ryoma would be good alternative choices, the former being a better choice since Myrrh and F!Grima are particularly common occurrences.
