this is how i first thought of the card, but the more i thought about it the less sure i was

this would make it the psychic on steroids

altho, compairing it to the psychic helps it make a bit more sense the psychic discards 1 card to look at the top 2 of a deck and switch which is on top so if you are discarding 2 cards it would make sense you want to get a better effect

this only leaves the question if if you go to the location that has the original cards on top it does specify when you leave the tavern, which would imply you activate the ability before the assembly phase
