I do not often compare at what cards is used most often in battles because the info usually cost some $$$ to obtain. Back in the beginning of Splinterlands this type of info was share among many different platforms and helped players like me know which cards had more uses.
However one site that still has this feature and free for all to use is:
https://kiokizz.github.io/Splinterlands/battles.html
On here players can select between wild or modern at different ranking leagues.
Interesting there are all 5 rare chaos summoners in top 6 most used cards in diamond league.
How interesting in diamond league the most commonly used monster is VENARI MARKSRAT. A rewards card!
There are plenty of other configurations one can try in searching for most used cards per league.
Until next time thanks for reading!!!
