While I'm not keen on adding non-SPM legends like Shelob (from The Lord of the Rings ), Ishkanah, Grafwidow (from Eldritch Moon ) or Arasta of the Endless Web (from Theros Beyond Death ), I do think there are cards outside of this set that I'd love to run in this list

These items usually offer a lot of utility in the TCG, which is typically why they fetch higher prices than you might expect
