Giving up Deletion would be difficult, unless it is possible to make Depair hit as hard too. I really like your idea to hit dmg cap that quickly with Overclock. I have NS Yakumo on a team with Iphi, Wenefica, and ES Toova. He was also on a magic team with Iphi, Xianhua, and AS Flamme. If I use AS Yakumo on that magic team instead, should AS Flamme be replaced by someone else for more dmg and abilities, and if so, who? I have had some Stellar luck with free pulls lately, and got AS Yakumo and Xianhua in thr past few weeks.
Xianhua most likely. Non elemental magic attacker who can buff and debuff is great. Then again if you needed to survive, Yakumo AS along with Kumos AS can work as well. Full HP and MP restore on the entire party plus Yakumo is given Guard until the end of the turn. So really depends on what I needed but I favor damage and getting fights over quickly so Xianhua is who I’d pick
