Each line is the variant with the best win rate among those played enough times, not simply the most popular one. Win rates are smoothed so a lucky three-game build can't top the list. Not enough players have finished the same three items yet, so the core above is the three strongest items measured one by one. Sample sizes are shown next to every choice.
