A few land suggestions that I find helpful when building 5C: Ravnica Bounce lands, which return a land to your hand when you play them but tap for 2 mana in a two-color combination Odyssey Filter lands After heavy reprinting in precon commander decks, most of these are under a dollar and sometimes as low as 50¢. They essentially act like Ravnica signets, but only in allied color pairs Pain lands: These vary depending on how often they have been reprinted, but some like Caves of Koilos go for 1$ or less. The Theros temples, Innistrad show/strixhaven snarls, and Zendikar battle lands are also good budget options
