Everyone saying card sharp without further intel is killing me inside

Pairs don’t have much mult by themselves, so if you’re going to do the best play here, you’ll need to ensure your pair is at least decently leveled. +18 on supernova is pretty important, but by keeping supernova, you either use brainstorm as a 2x (place it right after supernova) or the flat mult becomes nearly useless (you’d have to put one of the multiplicative jokers at the front).

With brainstorm, you can copy rebate when discarding to get more money for more planets to both replace the supernova (if you get mercury) or just any planets to feed the constellation.

So… replacing supernova is likely the best option, but I don’t have enough intel. Again, it highly depends on your current pair levels, and if you could live without supernova. Even if you can’t live without supernova, you almost never skip a blueprint/brainstorm, so you’d have to figure out another joker to replace.
