If I do it, It'll look way worse, I'll leave this to the professionals.
Well Jason-Chan, lets take a look at our options for white library matters cards.
First of all, what does white usually get to do in terms of getting more actual cards or searching:
- It can search for small dudes or tribal dudes
- It can search for auras and equipment
- It can search for plains or sometimes under special circumstances it gets to look for any land
The ways it tends to get extra cards that have nothing to do with your library tend to involve
- Making token dorks
- Armywide Bonuses
- The odd cantrip
- Damage redirection
- Wraths and killing creatures that have been committed
- Oddly proactively negating cards, like banning them or stopping search or removing abilities
- Sometimes it gets to reanimate specific shit
White also seems fairly proficient at stopping untaps, searching the library and scrying
So I figure the top list is probably the most reasonable for
Courser of Kruphix or
Future Sight style abilities. Abilities that care about those types of cards and then you get to do something fun when it comes up. But that's sort of shallow right?
The 2nd list could be bonuses it gets from the top of it's library for some reason or another, and since tapping, untapping, shuffling and scrying are all white abilities, it seems not unreasonable that it could be the enabler for these sorts of strategies, rather then the beneficiary. Say it does a lot of
enlightened tutoring?
Some ideas:
Royal Herald 
Creature - Human Soldier
When Royal Herald enters the battlefield, reveal the top card of your library, if it is a creature card put a 1/1 white soldier creature token into play, if not you may put that card on the bottom of your library.
2/2
Guiding Ancestor
Creature - Spirit
Flying
Play with the top card of your library revealed.
At the beginning of your upkeep you may shuffle your library.
1/3
(It would be no great thing to add a tap to this and swap out or make it more expensive for vigilance)
Inspired Artisan
Creature - Human Artificer
Vigilance
Play with the top card of your library revealed you may pay
to put any Equipment or Aura card from the top of your library into play without paying it's mana cost (legal targets allowing).

Favored Warrior
Creature - Human Cleric
When Favored Warrior enters the battlefield search your library for an artifact or enchantment card, reveal it and put it on top of your library.
2/2
Military Might
Enchantment
Play with the top card of your library revealed, as long as it is a creature card creatures you control get +1/+1.
When Military Might enters the battlefield put 2 1/1 white soldier creature tokens into play.
Might of Arms
Enchantment
Play with the top card of your library revealed, as long as it is an Artifact or Enchantment card creatures you control get +1/+1.

(this one feeds itself right)
Famous General

When Famous General enters the battlefield search your library for a white creature and put it on top of your library.
Play with the top card of your library revealed, you may play creatures on top of your library as if they were in your hand.

Some of these are kinda busto but I'm sure you're all capable of using these ideas in whatever way you see fit.
