Need help with Dimir Reanimator tech sideboard decisions (Daze, Strip Mine, Frog vs. Bowmasters, Brazen Borrower)

First of all, good afternoon everyone!

I’m recently returning to arena and just built Dimir Reanimator. A lot has shifted in the meta, and while I'm experimenting with a few different builds (for now, the scam package seens to work best), I’m having a hard time optimizing my sideboarding choices.

I’ve already read the excellent guide on Metaconfluence, but I’m looking for a more detailed sideboard guide or some insight on specific match-up dynamics (especially Play vs. Draw nuances).

A have a few other questions:

About the counters - Daze and Stern Scolding. When is the right time to trim or fully board out Daze (e.g., on the draw)? How do you properly evaluate when to pull Stern Scolding?

Strip Mine**:** run Strip Mine setup in all matchs, or are there specific matchups/builds where you leave it out?

Brazen Borrower**:** I've seen some lists running Brazen Borrower // Petty Theft in the sideboard. What is the objective here? Sneak & Show match-ups?

Orcish Bowmasters over Psychic Frog: Some builds cut Psychic Frog from the main deck entirely to run Orcish Bowmasters instead. How has this variation been performing in the current meta?

Thanks in advance for any insight.
