And bouncing has a lot of flexibility as a way to survive removal or blocks, adding a useful tempo element, reloading a creature with a powerful enters-the-battlefield trigger, dealing with auras and so much more
This is an easy way to get one last big push of lore to end a game, or just get a bigger lead to add more pressure to your opponent
