I flipped through it and while I don't see anything that would be competitive, the best synergy I see is a white weenie style deck.
Ajani's Pridemate can get big with life gain. (pump them with
healing salve, etc.) You have lots of 1-mana pump spells and lots of 1-2 drops with target effects that pumps them (and the team) permanently, so
favored hoplite curving into
precinct captain,
phalanx leader,
fabled hero, etc. )
Lone rider might be a good way to pump the pridemates and if you have enough other life gain going on, could flip and become pretty cool. You have some good value 1 drops.
Thraben inspector,
doomed traveler etc. Look for ways to synergize the life gain and pumps,
pride guardian, etc.
To Mnemosyne's point, if you throw a deck together (maybe as outlined) might be a lot easier to tweak from there.
* edit:
seeker of the way is great too for prowess beats and lifegain.
