Okay I'm not great at stay stuff, but here's what I can do. Phyrexian Rebirth is a must, Exquisite Archangel is not great, Herald of Anguish is really not great, especially for its cost, it's worth considering whether Sun Titan does enough, as well as honestly Zur the Enchanter. Maybe this should just be a Sen Triplets control build?

Well that was just plain unhelpful, if I wanted someone to tell me all the things I shouldn't play I'd be on reddit.

Sorry I couldn't be much help, though a lot less sorry after I read your response. Yeah I don't really do control. It costs too much $$ and it's not fun to pilot OR play against. So... sucks that you got my comment, I guess.

Enchantment removal like Journey to Nowhere or Darksteel Mutation seems like it would be broken with Zur

Some staxy enchantments like Frozen AEther would probably also be good.

And come on guys let's keep it civil, part of what makes magic so interesting is that there is so much diversity of play, that's why everyone hates format warping cards.

Path to Exile m y g u y, its too good to not use! That and Swords to Plowshares, auto staples for any deck with white imo

What do you think about Sheoldred, Whispering One? She's gone down in price a lot recently and would help reanimate your things while making opponents get rid of theirs. I would be careful with shroud since you can't equip anything or enchant creatures when they do have shroud. This seems like a very fun and interesting deck +1 from me

You're a little light on card draw/advantage. A few cards that I think are absolutely amazing are Fact or Fiction and Dig Through Time. They are great late and early game, and offer a great advantage. You also are missing the two most important spells in any white deck Path to Exile and Swords to Plowshares! They're amazing!

Also a great land to pitch things to the graveyard is Cephalid Coliseum.

I would try to keep your one creature alive at times that you think you need a board wipe. These board wipes will give you more fodder for finding resurrection targets. Consider Slaughter the Strong, Retribution of the Meek, Divine Reckoning, and Tragic Arrogance. +1'ed

also have you considered going with more land?
