Hello @beelzael. Thanks for comment.
I've analyzed the dynamics of Splinterlands for years, looking for signs that it's a great idea to invest in the game, but unfortunately I always come to the same conclusion: the game's mechanic is broken. Investing in cards is supposed to give you greater chances of winning, which is false and even to the point that it can almost be considered a scam.
I totally agree with you that strategy and tactics are very important in the game but not to the point that they are the only thing that should count. That is exactly the problem with bots, the algorithms have discovered the combinations with the fewest number of cards to win the greatest number of battles and therefore it is not necessary to invest almost anything at all to extract money from the game.
Take, for example, this battle in which my opponent uses at least 720 cards, while I only use 7 to beat him. It's crazy. Or this other battle with the same result.

The order of preponderance should be investment first, strategy and tactics second, and luck last. That is, if the players have the same level of investment in the game, then the strategy is what should decide the battle, if not investment should always have an advantage when it comes to battle.

This is the only thing Splinterlands requires to foster a real in-game economy.

Greetings and again thank you very much for commenting.
