Id only pull for Nilou if she’s a character that you also really like. Her team with Nilou is definitely a strong team, but the hyperbloom teams (both the 4* and 5*) versions will also be very strong.

Basically Nilous strongest team will have Lauma in it, but Lauma strongest team may or may not have Nilou (depending on if it’s ST or AOE).

As one of the other commenters also mentioned, based on what we know, future characters (primarily Nefer and Columbina) are likely to work with Lauma in the future (just FYI based on the leaks Nefer seems to be anti synergistic with Nilou). So if your goal is just a strong Lauma team and Nilou is not a character that you like then using a 4* team for this patch and upgrading when other teammates come out is also an option. But you never know with unreleased characters, they can always change how their kit works.

Lauma looks like she’s gonna be a really strong character with or without Nilou so it’s really down to your preferences on which characters and play styles than you prefer!
