Although Axie Infinity is one of the top-earning NFT, I do not know how to play and I think the price now is too high to buy for playing the game. I prefer to trade it and make money from trading instead of from the game.
But we know that the Axie is not the same as poker but that game can be the one game that can earn money. Poker is not easy to play as we imagine as we need to know the rule. But with learning from many sources, maybe people do not have to spend a long time to know how to play poker. I only know traditional Remi, as iv4n said.
Today buying your own team in Axie Infinity is expensive and I remember the first time I saw the price of axie's which is only a 2 months earlier the floor price was around $150-$200 now the price is doubled. But honestly this Axie game was not related to poker but yeah through this game people can earn a profit out of their investment. And as far as i know there's no alternative to poker and gambling related activities was a luck and skill related.
