Gotta love Karakai's Moonbeam <3 And circlet of acuity is the best legendary item for sure. Together they are amazing <33333 Love this team.
Two little thoughts/tips:
1. Chip's Replica is very strong generally, but I advise against it on an infinite run, because you should have the time and resources to find items around. It is incredibly useful on regular runs though!
2. Try to always get aurite shards on their tiles, when they come up, and ALWAYS use the "Rescue" option when you defeat bosses. This way you not only are sure to reach 6 max lv monsters at the end of the 3' round, but you get to "sense" and choose from three monster without paying the first 50 aura that you usually pay in normal egg tiles!
I see you are already pretty good with getting the right synergyes around, so I'm sure you'll be able to use the "sense monster" well! :D
