Sydney gave the market two different stories at once. EDG Rico1997 won the 1,405-player Regional Qualifier with Irelia Tempo, but the finals table also showed a $435.86 Sivir Aurora deck. That is exactly how players get baited. The winner matters. The expensive finalist matters. The buying decision is not the same for both.
The cards with real demand
Irelia Tempo staples
The cleanest post-Sydney demand is Irelia's Calm/Chaos shell. Rico won the event at 14-1-1 and Ghosterdriver put a second Irelia list in fifth. That gives players a simple reason to buy the package: it won, it duplicated, and it is cheaper than the Aurora finalist. Defiant Dance, Irelia, Fervent, Ride the Wind, Boots of Swiftness, Guardian Angel, and the cheap interaction around them should stay liquid because people will actually register the deck.
Sivir Aurora, but only if you need it
TSS SouledOut's Sivir list is the obvious headline for expensive cards: Dazzling Aurora at roughly $68 on the RiftDecks list, Elder Dragon around $32, Last Rites around $27, plus Sabotage and Stacked Deck. The deck reached second, so demand is real. The problem is timing. If you are buying after everyone saw the result, you are probably paying the event premium unless you need the cards for an imminent tournament.
Diana Tempo overlap
Diana put two pilots into the Top 8, which makes Mind/Chaos Tempo cards safer than a one-list spike. The overlap with the broader Tempo plan is the point. Cards that fit both Diana and other Mind/Chaos shells are better buys than narrow Diana-only pieces, because the demand survives if players switch legends but stay in the same tempo lane.
Hook Leblanc watchlist
CTCG DZiden's seventh-place Leblanc list is the sleeper market story. Harnessed Dragon, Baited Hook, Spectral Matron, and the Mind/Order support package are no longer just a CN theory. The deck costs over $400 in the posted list, so do not blindly buy the whole thing. Watch the package cards first, especially the ones that cross into other Hook builds.
The trap buys
Do not buy every card from the second-place Sivir list just because the deck looked flashy. The list was expensive before Sydney, and the result gives sellers a reason to raise prices. If the card only belongs in exactly that Aurora shell, wait for the first post-event wave to cool unless you are registering Sivir right now.
Do not chase Midrange generically. Sydney's Day 2 data had 457 Midrange decks, 36.8% of the listed field, and only two Top 8 finishes. That is not where I want to park speculative money. Buy Midrange cards because you need them for a deck, not because the archetype was popular.
Do not buy Annie Aggro as a sympathy rebound. The deck had attention going in and failed to convert. There may be a future version, but Sydney did not give you a reason to pay up for it today.
What I would actually do
If I were buying for play, I would finish Irelia Tempo first. It won the event, had a second Top 8 pilot, and does not require paying the full Aurora tax. After that, I would pick up Diana overlap pieces that stay useful across Mind/Chaos Tempo shells.
If I were buying for speculation, I would be more selective. Hook package cards have the better upside because fewer players were already staring at them, but that only works if the card has use outside one exact Leblanc list. Narrow cards spike fast and strand you faster.
If you already own Aurora cards, I would hold through the next major event rather than sell into the first wave. Sivir finishing second keeps the deck relevant. It just did not win, and the market should price that difference.
Price context
The posted Sydney standings list Rico's winning Irelia deck at $147.56, TSS SouledOut's Sivir deck at $435.86, nice boy's Diana deck at $300.91, AshenOCE's Teemo at $166.76, and CTCG DZiden's Leblanc at $422.56. Those numbers are a useful snapshot, not a guarantee of what you will pay after the market reacts.
The rule is simple: buy the cards that gained repeatable tournament demand, not the cards that merely appeared in the most expensive screenshot. Sydney made Irelia and Tempo safer. It made Aurora still relevant. It made Hook worth watching. Treat those as three different decisions.
