I do not know why (based on what I see from other players, the rewards still did not became any better), but after almost one month of break from playing Splinterlands (since 2022.02.06), I returned to playing the game, and today I achieved my 4000th win in Splinterlands.
My 4000th win is against @layla388, which is probably a bot.
This battle was a magic against magic battle. It was a 12 mana battle. Probably it was a good idea to use the Kelp Initiate in the first position. That card took five damage instead of the attacker cards. And I could have used the Furious Chicken too, but I forgot it this time.

By the way, I am playing Splinterlands since 2018.12.30. A part of my Splinterlands card collection is still on the rental market since 2022.02.06, but because I returned to playing, probably I will remove the cards from the rental market to be able to play with them.
Good luck and have fun.
Have a nice day. All the best. Greetings and much love from Hungary.
