Three things to ask yourself before you use:
How much do you hate Psi games? Caprice Nisei, Psychic Field, and Voter Intimidation are all awful to lose, but improving your chances from 33.3% to 50% kind of sucks. But if you really can't win a Psi exchange, move on to point 2:
Is there a better way to reduce the corp's money reserves to take them to 2 or fewer credits? If you manage Vamp or Account Siphon lock on them, they already can't spend the cash to rez ice, let alone spend money on psi games. So, if you are an influence-starved Shaper who hates psi, keep reading:
Do you see enough Jinteki to justify this jank? Psi games, while annoying for the runner, are almost exclusively seen in Jinteki, with the occasional influence splurge for ETR Waifu. Unless Nisei Division: The Next Generation pops up in your meta, put this in the binder and you'll be fine.
