"I Know Where it is!" from Hero Pack One

[aldrichgreg]

so, I just got Hero Pack One, and I am confused by the wording of the card "I Know Where it is!"

the words read:

Event
PLAY IMMEDIATELY
Play this card on a Random Building. Any Hero in that building may discard this card when when Searching there to instead look through the Hero Deck and take one Item card of their choice.
Remains in Play.

okay, so I am confused on the rules of this card. so let's say that Billy has this card in the center of Town. he plays the card ("Play Immediately") roll a 6 sided die to find the corner, then to find the building... we'll say Farmhouse.

The card is marked, "Remains in Play" so I assume it doesn't go directly to the discard pile?

But a Hero needs a copy of this card to discard it in the Farmhouse... so the copy does go to into the Discard Pile (otherwise it wouldn't reach the discard pile until the Zombies canceled it right? eliminating it's effect altogether?) now a Hero must find a way to recover the card from the Discard Pile get to the Farmhouse and then take any card from the Hero Deck?

is there a simpler way to interpret this card or something that I am missing people who have been playing with this expansion?
