There arent a large number of lands to choose from, but here are the ones you could use for this deck
What Land deck doesn't want to play and crack a Wooded Foothills from the graveyard to get a land and four landfall triggers, making four elementals with Omnath, Locus of Rage, drawing four cards off Tatyova, Benthic Druid, or doing all the things off Omnath, Locus of Creation
A few nice picks focused on Strength and lots of decent cards for budget decks
