First question: Why not [scryfall]Ezuri, Renegade Leader[/scryfall] or [scryfall]Kamahl, Fist of Krosa[/scryfall] instead? Ezuri is easy. I don’t have to limit myself to elves. Kamahl is a bit more difficult. First answer is I have done Kamahl and Baru is something new. Second answer is that Baru can bring something quite unique to the table. Each of the ramp spells in your deck becomes a mini-[scryfall]Overrun[/scryfall]. Or in some cases something much, much more.
