Does Myriad Landscape work with two of these things?

This seems to have no mana ability. Is that intentional?

I don't think Myriad Landscape will be able to work, because this has no Land Type. For example, Wastes don't have a land type, so you can't fetch those, even though they're Basic.

That's incorrect. Myriad Landscape can fetch one Wastes, but not two, since they don't have a land type to share. Likewise, it could fetch one of these, but not two

I googled the question again and looked for more answers, and dude1818 is entirely right!

"So… Wastes doesn’t have a land type. This means we can’t search up two Wastes with Myriad Landscape since they don’t share a type with each other.

This leaves the big question of can we search for one Wastes? Is having a basic land type required to be found at all?

No, you can find any basic land if you’re only searching for one land. Sharing a basic land type only matters if you find multiple lands.

This was clarified with an updated Gatherer ruling in 2018."

So... yea! Can fetch one but not two. Today I learned, thank you.
