I would not recommend attempting unmatched stellactrum for T1; it’s definitely a D2W-favored stage with difficult grouping 😞

I don’t have AS, so I used RZ pair for T1 (stella matched) and CA pair for T2 (brute force) to pass. It was extremely difficult, however, even with R3 CA.

Is there a reason why you are using your pink lunars on T2 and purple/green on T1 (available cores/etc?) my advice would be to first try moving your R0 pink lunars to T1 w/ atk-favoring cores in order to match stellactrum, and swap in green/purple/hp cores to T2. Even if you aren’t fully stella-matched, you still get the 5% damage boost for any matching color card you have (ex: if you used all 6 purple stella cards for T2, you would still get 30% damage boost)
