The Thresh Sejuani synergy stats shown here demonstrate the areas of his gameplay that do better (or worse) when paired with Sejuani, compared to his overall stats. Significant differences are areas of focus that highlight how his gameplay changes when paired with this other champion.
Overall, Thresh sees a large worsening in his KDA (ratio of kills and assists to deaths) when paired with Sejuani. His KDA went down from NaN to NaN. This worsening shows that Sejuani helps Thresh perform worse in competitive League matches. Yet, the small difference demonstrates that this performance change is only marginal.
When Thresh is an ally to Sejuani, he gets a marginal improvement in his complete damage output. This change may indicate that Sejuani helps provide protection for him to deal more damage or that her support also helps extend the match's duration. Similarly, when Thresh is played together with Sejuani on the same team, he usually scores many fewer killing sprees than when he plays without Sejuani. This is contrasting evidence that he is worse when playing synergisticly with Sejuani.
Additionally, when Thresh plays with Sejuani on the same team, he usually takes a little more damage than when he fights alone. Getting dealt more damage could indicate that Sejuani does a poor job of covering Thresh in team fights.
There is no universally accepted best companion for Thresh that will always be his best teammate. Yet, Sejuani is a very bad companion for Thresh. By locking into the same team as Thresh, she drops their win rate by -4.6% to 43.9%. This clearly indicates that there is an easy to overcome and exploit synergy between Thresh and Sejuani that results in them performing not as well together than without each other.
