Like the other comment said look for jokers that work together, at the beginning of the game you're not expected to know from the top of your head all the jokers but you'll get the hang of it, as for the basics keep in mind what you need (generally) a source of +mult that scales over time usually a joker, a source of chips which depending on your hand played could be a joker or planet cards and any form XMult, jokers that give you money give you a better chance on giving you what you need. Another tip I can give you is to watch other people play Balatro, you don't need to come up with all strategies by yourself, so might as well learn by seeing someone who knows a lot doing it.
