My favorite creature in WUB is probably Sphinx of the Steel Wind. It lacks the disruptive potential of most of the cards in the OP, but it's a solid beater. Find a way to give it pro-white or put some boots on that cat and watch it tear up the curtains.
(Have you ever looked at its claws? They're pretty great.)
Kederekt Leviathan is a solid board wipe when a reset is needed, I ran it in my Zur the Reanimator deck I played a few years back and made good use of it.
For me, it's hands down Magister Sphinx. It's also very castable from your hand, and in a zur deck, you will have more than 10 power on the board sometimes.
Sorry to ask a slightly off-topic question, but I'm assuming you're using Zur for this deck because of his interactions with Animate Dead, Necromancy, and maybe Angelic Renewal, but what other reasons do you have for running Zur? Just general power-level?
Looking for the best creatures to reanimate in UWB for my Zur the Reanimator deck.
So far I have:
Also, Vish Kal, Blood Arbiter, Karmic Guide, and Reveillark... You have be running these in a BW reanimator deck.
You could look at enchantment based sac outlets to find with Zur as a way to develop this theme.
Also, see...
Blazing Archon
Platinum Emperion
Reya Dawnbringer,
Stormtide Leviathan
Tidespout Tyrant
and Trench Gorger.
