I could pick the jack of spades out of a new deck of cards too; they tend to come pre-sorted. All it takes is studying another brand new deck of cards. (I’d have to do this studying before I would be able to pull this trick off, though.)
My guess is that you’d want to flip it backside-up, and from the then bottom, pull 10 cards and flip the top one of that one over. Then you’ll have either a Jack (if it starts with an ace, I assume this to be very likely, 50%?), a 9 (if it starts with a placeholder card, like a rule card, I presume this to be probable… like, 20%?), a Queen (if the ace is last, a la Jack Queen King Ace, 20% for this one as well) an 8 (two jokers at the front of the deck? 8%?), a 7 (2 jokers AND a rule card?! 1%) or 1% of me just being wrong entirely. It sounds like a weird distribution, but rule cards and jokers tend to be at the back, and an ace with fancy artwork tends to be at the front of the deck because it looks good.
A bit of googling reveals that a new deck usually starts with the Ace of Spades, so I’d guess that flipping the deck over, then drawing 10 cards from the bottom of the deck (what used to be the front) and then flipping the 10th card over will give you a Jack of Spades.
