Deck Gap Guide
Current format: Ruler of the Skies (B4) · What the top decks need, checked against real claim data
What this page answers
There are plenty of sites ranking decks; this page is not another tier list. It handles the question that starts after the ranking ends: of the strongest decks in the format, which card are you missing — and can you get it right now?
Where the two datasets come from
- Tournament data (external source) — deck share and win rates are cited from Limitless TCG's B4 Standard statistics, a sample of 122 tournaments, 11,566 players and 30,158 matches, retrieved 2026-09-01. This is third-party tournament data, not produced by this site and not an official source; this site does not rate deck strength itself.
- Claim data (exclusive to this site) — 258,914 delivered claims from 7,026 unique players, counting only requests that reached the Delivered status. These are votes cast with an allowance players only get once a day, and the rankings here are recalculated every time you open the page.

The most overlooked card this format
Mega Lucario ex — it is the core of the format's #1 deck (9.39% share), yet only 126 players have ever claimed it here, ranking 228. Cards that are strong but untouched usually share one cause: they come from an older booster, pack-opening attention has moved to the newest set, and new players never go back. For an allowance, this is the best return available — and with nobody competing for it, it is in stock almost around the clock.
The key cards being missed
These cards sit in top-tier decks yet rank past 100 in claims here. Nobody is competing for them, so your success rate is at its highest.

Three rules for topping up
You can claim two cards a day. Delivery and trade run on separate allowances; use each once on the same day and that is two cards. Headline ex via delivery, partner slot via trade, and half a deck moves forward daily.
Take the unpopular card first. Cards in the top 10 above frequently run out of delivery accounts at evening peak, while partner slots ranked past 100 almost never fail. Claim the obscure one during peak and save the popular one for the quiet stretch after the 14:00 reset.
Star and Shiny prints go through points. Every link above points to the ◆ version that can be delivered directly; Star and Shiny prints of the same card do not use the delivery mechanic.
