Finally got Tsukuyomi to round off my Light team (Sol, Tsuku, Michael, Diana). Fire would've been another option, since I have Amaterasu, Ares and Yamaraja as well as all notable SRs, but since Light's always been my main, is as good for off element as you can get and only lacked some more damage, Tsuku definitely fit better.
Guess all that's left for Light would now be SSR Artemis or maybe Raphael/Eros, but the later ones can still be subbed with Belobog if really necessary. Generally my current team should do though.
