The name is the exact same as the set from 1998. Probably the most broken set/block ever.
It’s the first enchantment land in the game excluding test cards. This is a homage to the Urza’s Saga block that was themed around enchantments.
The first chapter gives Urza access to colorless mana. Very fitting for the planeswalker who dealt with colorless artifacts and
powerstones his entire existence.
The second chapter creates artificial life. Just like Urza did with Karn and even taught Karn how to copy. This is how the plane of Mirrodin came into existence.
The third chapter is a tutor ability for an artifact that Urza’s Saga block was famous for like
Tinker.
On the art you can see three levels or layers. There’s the almost erased in the background. That’s the writing of Urza’s wife, Kayla bin-Kroog from way back when Urza was a creature. Then there’s the clearly visible writings, formulas, graphs and calculations. Those are Urza’s own writing from his era of being a Planeswalker. Finally there’s the paintings in the foreground. There’s the book in the middle of the art, the
Skyship Weatherlight in the bottom right corner and in focus we see High Lord Urza himself in his prime as the strongest being in the multiverse. This is done by his old friend, Barrin, who took over
Tolarian Academy after Urza’s death.
