Can I play this game as free to play?

Hi, disclaimer: I'm a total newbie at Magic.

I'm a bit interested in trying the game, I really like the artworks but I've never actually played it.

As the title says, can I play this game as free to play?
Or will I need to spend money to buy packs because the cards rotate?

I've played Hearthstone in the past, but that's about it.

Thanks
