Start here
The legends appearing most often in top cuts right now are Master Yi, LeBlanc, Diana, Irelia, Vex, Azir, and Sivir. That does not mean you sleeve the first name you recognize. It means these are the seven matchups you should be preparing for. Representation tells you what to expect. Conversion tells you what wins. Both numbers matter.
Representation vs. win rate
A legend with 18% of the field and a 52% win rate is a safe, tested choice. A legend with 4% presence and a 68% win rate from 20 entries is an edge pick for a prepared player. The common mistake is treating the popular legend as automatically correct, or dismissing the rare one as a fluke. Both require the same check: how many total entries back up the number?
What is climbing right now
Vex-based lists have quietly accumulated strong finishes. The reason: Vex punishes the slow, greedy midrange that most players default to. If Master Yi dominates your local field, LeBlanc and Diana decks with early disruption do well because they interrupt the setup turns Yi needs to function. Azir continues to appear in top cuts because the rune package gives consistent energy development, which matters in long games.
The mistake most players make
One undefeated run at a 12-person store championship gets posted everywhere and makes a legend look dominant for a week. Then the field adjusts and the deck settles back into the pack. Before you switch decks, check three things: total entries for that legend across tracked events, average finish position, and whether the card core has changed in the last three weeks. If the core is stable, it is a meta pillar. If it keeps shifting, the field is still adapting.
