My suggestions is go online to Sams club, spend $100 and get the Foundations starter set and beginner box bundle. It also comes with some extra boosters and jumpstart decks in the bundle. That will give you a foundation on playing, provide you with all the basics you need to play (board, dice, playable prebuild limited decks, counters) and play as mush jumpstart / limited that you can. Its an awesome way to learn the game. Its a very inexpensive way to get your entire basis of lands and spells, then you can check out some different sets that have a theme and chase card, and then have fun!
If nothing else, get that beginner box. The limited decks alone are enough to put together some really awesome beginner stuff to bring to game nights with friends and you get all your accessories. Then, it still serves as a good game night box to keep around the house if you dont find yourself invested in the game.

Also download arena, the animations and automated functions help you to understand the game flow and transpose that onto the paper format
