With a deadweight active and no SBR, it's just really hard to fit him anywhere. Indeed he hits harder than the 'usual' double 7c hitters when the killer kicks in, but when looking at the overall package, for instance Tachibana's board change + 75% shield is far more versatile and valuable to pretty much every team out there. I guess he's better than what I previously described him as 'mediocre', but when considering his usefulness in his pixel form (see my explanation to kandjar), there's very little reason to not go with the pixel evo. To be fair, just the 3x3 awakening alone is enough reason to change Sephi to pixel. The other awakenings are just the icing. 3x3 is really the latest meta shifting awakening. Between Fujin, FUA and 3x3 (and to a lesser extent attribute absorb void), you have all the tools to bypass all the game's gimmicks. Also not only you get to OHKO some of the otherwise toughest bosses in the game (like Noahdra), it also makes team building a lot more flexible. Instead of trying to balance damage across the whole team, you can now just stack killer on your 3x3 sub without having to worry about uniform damage output from the rest of the team.
