You can use Canva (lots of beautiful, free templates + has a mobile app) or Designbold (cheaper pro version if you ever want to add your own fonts or save transparent gifs)
I use those two almost exclusively for social media posts (including tarot spreads) and only open Adobe Illustrator for more complicated things :)
How about this: https://www.designbold.com/collection/magazine :) This is a resource where I often find inspiration and sometimes when I get lazy, I'll use their free templates for quick results! :-))
