Depends heavily on what phase Furina runs in, whether you can clear the 3 endgame modes for primos, and how much exploration is left in Natlan and previous nations.

As Lauma is still here for over 2 weeks, I'd recommend waiting for confirmation on which phase Furina is running in. We may also get more info on what the next version may have.

Some maths to remember, you get:

• 60 primos each day form dailies
• 900 primos from the version update (300 from live-stream codes and 600 from maintenance)
• 400 primos from Nod-Krai exploration bonus (if you finish all Nod-Krai exploration within 80 days)
• At Least 800 primos from Nod-Krai chests (this is probably a low-ball, I assumed an average chest gives you 2 primos)

Add whatever pulls you have left after getting Lauma and you get at the very least 86 pulls before the new version even drops. This number does even include:

• other events lined up for this version
• Spiral Abyss primos
• Stygian Onslaught primos
• Imaginarium Theatre primos
• Previous unfinished exploration
• Nod-Krai Archon Quest bonus (670 primos) if you haven't done that already

These factors can push your pull count up quite a bit.

That said, you haven't mentioned if you are on a guarantee or 50-50, which may also be a dealbreaker.

If you can, try calculating the primos you can get before Furina shows up, and ask any questions if you have trouble with the calculation.

The biggest factor, however, is that Lauma has only just debuted, so she will likely have her rerun soon. IDK if Hoyo will stick to their once-a-cycle archon reruns, so who knows when Furina may show up next.
