Sorry, but next time please tag the deck as standard.

so is it a mono white control deck, or a blue white control deck?
instead of sphere of safety you could put ghostly prison or propaganda.
for creature removal you could put swords to plowshares.
Luminarch Ascension is a bomb.
Story Circle protects against most things.
You can replace ghostly possession with Inviolability.
Worship is also an alternative.

if hexproof is a problem put in a glaring spotlight.
if price isn't a problem then put in Bribery.

Reliquary Tower is a land that does the same thing as the spellbook.
Library of Leng will give you no maximum handsize, and if you discard a card you may put it on top of your library, so it works with Jace's Archivist.

Not sure why u need swamps, if it's only for dead weight,
path to exile
Rhystic Study is great for drawing cards...
Sigil of the Empty Throne for an army!

Godless shrine is also a cheap solution???

Isolated Chapel as a dual land.
Hour of Reckoning as a removal...

This isn't a deck and i think you already know that.
what is a dual land doing here if it gives you green mana???
and why do you have white and black cards!//?????

Concentrate instead of amass the components?

Momentary Blink is a cloudshift with flashback.
Sorry, but Nephalia Smuggler is an uncommon...
Since you don't have many ways of handling late games, I would put in mana leaks for early game.
In this type of deck, Loyal Cathar can die, and when he is transformed then you blink him and he's alive again.
Man-o'-War or Kor Hookmaster can each stop a creature, and Mulldrifter let's you draw.

Maybe Skinshifter?
