Creatures you exile from your hand so a land gains a mana ability until you cast them from exile, like Streets of New Capenna's Glamorous Outlaw and Emrakul, the Exigent Doom.
Track which ones you own in Mana Dork: it marks every card on the list you have, and there's an achievement for owning all 6.
