Whenever an opponent discards a land card, add to your mana pool

Though somewhat costly at six mana, this simple yet stellar green enchantment states that each of its owner's lands may be tapped in order to produce a treasure token

So I think that we may fall prey to board stalls in which the creatures youre eternalizing are just not going to be able to compete with with the rest of the table

The process you're repeating includes that check at the end to see if it's a land, so if you've only got lands in your graveyard, you'd get them all back as tapped tokens

Untaidake having so many restrictions is indicative of how careful R&D can be when creating lands which produce multiple mana, though its an example of a card so thoroughly underpowered, that its essentially unplayabale outside of EDH and the Legendary Cube
