I mean, Mystery Booster have lots of reprints that are significantly cheaper than their original cards, and there were almost 1700 cards in that set.
I, for one, am excited. We saw how well Mystery Boosters did reprint-wise, C20 wasn't as bad as c18 was reprint-wise, M21 had solid reprints, and now Jumpstart not only has fantastic, big-ticket reprints like
Craterhoof Behemoth &
Exquisite Blood, they have commanders like Neyith of the Dire Hunt that
explore new, unique design space. I really hope this trend continues with Commander Legends (and Double Masters although I will never be directly participating with Masters sets).
About the rare land cycle, I think they are best compared to trilands, as others have said. I would never run them in 1-2 color decks, would almost never run them in 3 color decks, and may run some in 4-5 color decks. I know that, especially when on a budget, it's good to lean into green in your mana base and rely on ramp like
Cultivate to consistently get your other colors, so running Thriving Grove to get green and the most useful color at the time could be helpful.

an ELF? Hoo hoo boi! It's only 1 mana, tells nasty blue players to piss off, and turns your elves into DINOS!!?? Slyvester, get over here and look at this beaut!
