Starfield of Nyx
Can't be tutored by Zur but it skips the need for Sun Titan or Reito Lantern, or even Zur having to attack more than once.
Also you're in Black and White. Unless your group has a thing against it, which would be dumb since they're already cool with you taking infinite turns, you should already be running many of them.
This doesn't actually work, unfortunately. Starfield and Second chance are both "At the Beginning of your upkeep" triggers... so you will only gain an extra turn every second turn.
I think you should ignore the above poster. Even if you figure out how to use gatherer, doesn't mean you want to go through hundreds of enchantments only to not find anything.
If you're looking through hundreds of options with parameters that specific, you haven't learned to use the tools very well. There are only 5 tutorable enchantments in Zur's color identity that do any kind of tutoring and only 94 that reference the GY in the rules text. If I can skim through them in 5 minutes, OP can do it just as easily.
Right, but sometimes the card you want won't come up if your wording is too specific. I think it is always worthwhile to ask the board for suggestions. Even if you don't get exactly what you want, you can get some ideas. While op was looking for tutors, someone could know another, more effective Last Chance combo that uses some of the same pieces.

I have seen enough Zur decks to know that there are no enchantments with CMC 3 or less that can tutor creatures, and none that can tutor a CMC 2 artifact. There is one enchantment that is like a blue survival of the fittest for artifacts with CMC 1.
I think there are two ways to dig for your combos.
1. Get some good life gain enchantments. This will let you dig more with Necropotence. Peace of Mind, for example, can work well.
2. Get some self mill effects... Fraying Sanity? Mill Sun Titan and reanimate with Animate Dead.
I love your idea of using Second Chance, but it will be hard to get the combo going just with Zur. You need other tutors.
