Many people despise it, but I really like this card. It is basically a Komainu taken trap form, activated with a Psi game, giving you about 67% chance of working. Doesn't work from R&D, neither from HQ or Archives, only installed - so, the usefulness of this there toy is mostly limited. Or is it?
Obvious answer - depends on the meta. If your locals play a lot of exposure gadgetry, this will induce rage and pain harder than an easily countered Junebug. Psychic field doesn't need to be advanced in order to work and has a trashing cost of 2, which may or may not help if accessed from somewhere else than the remote server - depends on circumstances, but it is better than whopping 0 of its rival and somehow justifies that you have to spend additional credits in order to fire it.
If I may make a suggestion? Toss it in, just one copy, if you will. See what it does. Maybe not in the first match, maybe not in the tenth, but at some point, it will fire. And you will laugh. And they will cry.
Now, if there was a card that would let you expose an installed card to the runner... Maybe someday it will - and then Jinteki will break the game to pieces.
EDIT: There you go! 419: The Amoral Scammer hates this card with perfect hatred. You've got a good chance of being just a won psi-game from an easy victory, provided you can follow up with Neural EMP or Ronin.
