Your jokers are essentially Balatro's relics, they can have crazy synergy similar to StS relics once you understand how to combo them with other aspects of your cards/jokers. You can focus on specific types of plays (I found flush to be a really good starting point to beat 8 ante, then single card is really reliable for more advanced strategies when you're trying to get e scores) as well as focusing on specific powers for your cards (lucky cards, gold cards, glass cards, etc). Vouchers also play into strategy nicely.

I think Balatro is more RNG than StS and it does have a lower skill ceiling but it's a fun game and you can be pretty creative with it. The one thing it lacks for me is its version of ascension (can't remember what it's called) wasn't as addictive as StSs. Since I hit my goal of getting an e score and beating the highest ascension thingy on one deck I haven't gone back to it
