You can see the decks' MTG commanders below, but first here's an overview: Terra, Herald of Hope leads the graveyard deck Revival Trance that can quickly assemble a large horde of low-power creatures, perhaps for some aristocrats shenanigans
Sauron, the Lidless Eye Sauron, the Lidless Eye has a good ETB effect and a nice mana sink that can drain a lot of life from your opponents in the right circumstances
