Well, it is kind of win more, but just Thopter-Sword always has to pass turn. So, there is the chance you could lose after passing the turn. With Urza though it is infinite mana and tokens and you can play your whole library if you want. Most importantly, can can keep "Apaturing" until you hit a Force of Will and prevent yourself from losing or having the board wiped. Plus, an arbitrarily large amount of life is a good deal better than an amount equal to your available mana.

But I don't know that it makes the combo super-Tier 1, but it does make it minorly better.
