Providing free card love for all, the Mine has been used in decks ranging from Prison (Icy Manipulator/Winter Orb lock) to Orim's Chant/lifegain
With its fair share of board wipes like Kindred Dominance and Decree of Pain, coupled with cards like Reality Shift or Chaos Warp to deal with troublesome Permanents, these allow the deck to act like a Swiss Army knife for removal, dealing with threats effectively and efficiently
For those looking for non-creature options there's Finale of Devastation, the classic Overrun, and the evil Triumph of the Hordes
There are so many decks to prepare for that your sideboard needs to work overtime
I speak of the undead here, so repeat offenders arent that surprising
In the aggressive decks it is so cheap and you are aiming to be ahead already that it is just a pretty good tempo tool
