Shingen works well with daji and titania though, as well as other burst increasing girls.
she fits perfectly on my wind team.. pretty much guaranteed double/triple atk with titanias combo buff on turn 1 (say it's burst time) so can use full burst with all buffs/debuffs on the second turn, OR use titanias ability dmg buff which would automatically get her from 70 to full... but would rather save that for Azazel since I can do over 600k dmg with that ability if i'm using hraesvelgr..
