Second the other comment by @[email protected] . Commander is a good way to enter the paper format.

However, before jumping in I’d recommend playing through the (totally free) Arena tutorial to understand the base mechanics. And don’t hesitate to ask questions or to read all the cards! Commander is an eternal format, so it has a huge history, I don’t even trust an old player who claims they know it all.

So there’s a lot to learn, definitely start with a precon and learn what works or doesn’t work for you.
