COUNTED, NOT PREDICTED

Ultimate Champion decks that win more than they get played

Each deck below clears the Ultimate Champion field's own average win rate of 49.3%, and is queued less often than an even slice of that field's games. Both halves are measured from real battles in the Ultimate Champion (leagues 6-7) bracket.

"Under-played" is measured against this bracket and no other: a share that is rare where four hundred decks are tracked is ordinary where forty are. The line is this bracket's own even slice — its total play divided by the decks measured in it, 1.53% each — so a deck qualifies by being rarer than it would be if the field spread its games evenly.

9 decks in this bracket carry enough comparable battles to be measured this way. Measured Aug 16, 2026

A deck the bracket board did not rank carries no model number. Ask for one and it is computed once, then cached — the next reader who opens this page gets it without waiting and without spending their allowance.

What makes a Ultimate Champion deck underrated?: On this page, two measured facts at once: the deck beats the Ultimate Champion field's own average win rate of 49.3%, and it is queued less often than an even slice of that field's games — the share every deck would hold if play were spread evenly. Both come from counted battles rather than from a model prediction.
Are these win rates reliable?: Each deck's rate is computed only from battles where both sides played a deck the bracket genuinely plays, and the two crawl orientations are averaged 50/50 rather than pooled. Every deck also carries the number of battles behind its rate, printed next to it, so a thin sample is visible rather than hidden.
Should I switch to one of these decks?: They win more than the field average in this bracket, so they are worth trying — but a rarely played deck is also a deck your opponents have less practice against, and part of the edge is that unfamiliarity. Score your own list against the same bracket in the Deck Lab before committing to it.
