How do I make this card worth playing? Rebuying a fetch or two really isn't something I think is something someone in my cube should spend two mana for.
Wastelands, a reanimator package, delve cards, and pretty much any way to create extra value out of the graveyard. You're not really looking for explicit value off just the Loam; you want it to help create value elsewhere via dredge and find ways to take advantage of that. Figuring out ways to extend your hand and available plays into the graveyard is pretty fun. I still haven't added my copy of Loam to my list (laziness), but it'll be in there soon enough. I like having the following cards to help build up reanimator themes. I've just added a few of these recently so I'm not sure how good they would be, but I'll let you guys know if anything really shines in testing. I'm just going to list out every card that might be okay in a Loam deck currently in my cube:
