Respect the face down cards
This card is all about making the runner respect placing multiple cards face down upon the field without ice at the same time. Is there an agenda?, are they all agendas? is there a trap?, are they all traps? which one is the agenda and which one is a trap? Making the runner think is the greatest strength of jinteki. One hit and failed psi game later and all of a sudden they find themse;ves with their entire hand being flushed.
Psychic field however, is different than other trap assets. It really demands complimentary traps to make it worth while so as to keep the runner guessing. If you're playing Jintek all you need is 1 snare in deck, 1 snare in hand, 3 breached dome protecting archives and now they have to respect running anywhere.
