Here is an easier way to do "Quarterly Triumph" --
Effect: You tell the spectator you're going to teach him the "Las Vegas 4-Point Inspection For Marked Cards."
He cuts the deck into four piles. All the piles are examined for marked backs, but nothing is found and the deck is reassembled and tabled.
You then tell him that, in fact, the cards are marked, and that you can immediately find the aces. The deck is spread (by the spectator) and he finds the four aces face-up in the middle.
Method: Four aces on top. Spectator cuts four packets. You pick up the ace packet, push off the top four cards, take them into your other hand in a squared packet.
Spread off some more cards (messily) take them on top of the aces, but keep them jogged, take some more cards, etc.
Now as you take the cards back into your dealing hand to square them, you can easily half pass the aces underneath (there's enough cover to hide an elephant). Rationale:looking for marks on the backs.
Square that packet up (top down: face-down cards, fours aces face-up on bottom). Spectator checks one of his packets for "marks," sees nothing. He drops this packet on the table and you drop yours on top.
Have him check the other packets. Assemble the deck with one of these packets on the bottom and on on top.
