So this and [[Lantern of the Lost]] will be in Standard at the same time.
Which is the better sideboard card? Lantern of the Lost doesn't make you choose between stopping recursion and drawing a card, but Soul-Guide Lantern doesn't make you leave one mana open just in case you might need to exile. I guess I'd give Soul-Guide the edge.
(Arguably there are better graveyard-hosers than either, like [[Lion Sash]], but let's assume you're going to run one of the Lanterns.)
