reason i want to borrow a Ryuutan is cuz i want to feel a direct comparison between him and Saberlot in a strictly 3 member party composition
So I tried Saberlot with Waver (olgamarie CE) and Tamamo (prisma cosmos) at first.
It went bad because Tamamo and Waver apparently isnt enough to cockblock Nezhua's NP from happening, and between the three, only Tamamo can stack enough defense to survive the NP. The debuffs from each break also prevents me to finish it fast and hard.
So i changed strategy. And im kinda surprised that I like Saberlot Mash Jeanne better than the Arts Trinity compo.
Mash can handle the defense from normal attacks (jeez Nezhua really hits hard), while I just need to make sure Jeanne's NP is ready every five turns, thanks prisma cosmos. i even get to pull double luminosite in the space of 5 turn.
Her starperturn skill's CT also fits snuggly with Lancelot's.
Overall a relatively relaxed run, because every angle was covered.
With Gundam's Ryuutan, I also tried him with Waver and Tamamo, but this time with 4060.
It went a bit better Ryuutan's NP spam is better from Lancelot if his teammate can give him stars, and he has dodge, so i can just put his own dodge, master invul on waver, and def stack on Tamamo to survive incoming kasensou if i no longer am unable to reduce Nezhua's NP gauge.
But then the second NP hits me anyway and kills Waver. Tamamo still survives and so does Ryuutan because the suiten nikkou reduces CT, but without Waver's def up they both died faster.
I also found out that using 4060 on Waver and Tamamo actually hinders their NP fill quite considerably compared if I put olgamarie or prisma cosmos. I thought the arts crit could make up for the per turn NP fill, but apparently not enough.
So a change of tactic, I bring Ryuutan with Mashu and Tamamo with NPperturn CE instead of 4060 to capitalize on the def up and atk down instead of crits.
It actually feels very similar to my Ibaraki team; that is, it was very engaging, making sure every 5 turn i can go 100% def up while also making sure i have enough def up between each 5 turns to deal with Nezhua's normal attacks
I like it that the team felt very balanced. My only problem was that every time Ryuutan do Mutoudori i prayed PLEASE DONT MISS PLEASE DONT MISS because if that debuff miss, then thats it, the team's ded lol.
TL;DR i went in wanting to try Ryuutan's and Lancelot on same team because my friends and most people really likes to compare the two, but I found in my experience that the slight difference in their kit actually makes quite a big difference in the demand of teammate composition as well
