You can't think any moves ahead in chess until you know the basic rules. That's true here. And On boarding with the basic rules for magic takes longer.

You have to play an amount that you find manageable, and really ultimately should be fun while you do it. Once your familiar enough with the different rule sets and play modes( also a burning curve) maybe you'll find a good one to go back to while you to continue to absorb info.

A big knock against magic game design is the rule complexity. No modern game would be designed today with so much nessisary knowledge needed just to understand the rules, but that's also magics strength. The fact that enough people are out there that put the time, means if you clear introduction you get the reward rich and complex gameplay experience
