Most books have abilities that draw cards, though some find other ways to give you value, like how Monster Manual mills you, returns a creature to your hand, then lets you put a creature onto the battlefield for 2 mana
This crossover is also based on the books rather than the movies, which means that characters like Tom Bombadill are in play, as well as the creative team having more freedom to imagine the world as they see fit
To ensure you get there, you can get plenty of value out of token makers (note that Marneus draws off treasures too)
