Sakura-Tribe Scout feels more powerfull to me than the grazer, especially in the context of their respective sets (i.e. the moonfolk that bounced your own land). Thats not even considering how much stronger creatures have gotten on average since.
The scout has to last a turn before it has an effect so you can't benefit from the acceleration until turn 3 at the earliest, while the beast immediately works, has a far more impressive board presence, and is legal in far more sets. I'd say that's going to make it better for all but a very tiny number of decks that constantly replenish lands in their hand and need ways to keep putting them on the board.
