8bitdo macro tips for random encounters?

Maybe this won’t work. but does anyone have tips for using 8bitdo macros to shiny hunt static and gift encounters? I’m not familiar with how seeds and advancement works, but I’d like to ideally buy the 56 abra and have a macro that paces the buttons randomly enough to make sure I’m not repeating seeds if that makes any sense? I’m not trying to RNG manipulate as much as I am trying to use a macro to buy these without repeating the same batches of mons. Thank you!!
