This is my first time building a deck of this type and I'm kinda stuck. I could really use some help with this. My budget is max. 25$ (incl. shipping) and the deck is currently at ~14$ (with shipping) on TCGPlayer. No Planeswalkers, my playgroup has an agreement that we play without them. http://www.mtgsalvation.com/decks/1367-orzhov-enchant
for protection from removal: mother of runes, very powerful card, useful in any white creature deck you will ever build in the future
or swiftfoot boots

kor spiritdancer, this one is expensive but very powerful, if you add it consider adding pacifism, prison term or faith's fetters as removal
for protection from removal:

predator's gambit is a better unholy strength
for defense:
ghostly prison
sphere of safety
