mavuika's C1 or citlali's C1 ??

im kinda only going to be able to get one or the other. which would net more damage in the short term? cause dmg wise in her best team, mavuika only gains 40% atk from the C1, the extra fighting spirit is kinda useless there. The most valuable thing i see about it is getting stronger to C2.

But im kinda close on beating stygiant 6. im only missing the hydro tulpa.... i already have mav's sig.

will mav's C1 help me clear stygiant or will citlali's C1 be better for the moment? (i can try and save for mav's cons in the future)
