Kushinada + Bastet was a very common combination for combo players in the past, as one (bastet) ensured that lower combo numbers still packed a punch, and Kushinada assured that your multiplier would keep growing pretty much forever.
Of course, nowadays that kind of combo is considered "outdated" (as anything that isn't god-tier is) and kushinada is mostly relegated to sub status.
Not outside of tri-color,
I have actually have 20 combos outside of tricolor once :V
Of course, it didn't matter because it was a killshot regardless, but still.
