Four days ago, I wrote about my My first PvP battle in Thetan Arena (2021.12.19).
Let us say that I tried this game, so you do not have to.
Since then I played dozens of battles. The game seemed/looked like fun at first, but actually it is not. The problem is the fact that it is impossible to climb up on the ladder, because you receive and lose the same amount of trophies (24) for winning and for losing.
I played for hours and hours, and I lost approximately the half of my battles. I am stuck between Recruit III and Recruit IV.
The game gave me three heroes at the start, but all of them are Non-gTHC, so I cannot earn with them by winning battles.
If I check the store, then it is also full of Non-gTHC heroes. There is no THC heroes there.
So much for the "best" blockchain game.
Conclusion: I rather keep playing League of Legends: Wild Rift for free. At least that game is fun, entertaing, enjoyable, and it is very much possible to progress in it.
