I usually don't make my decks public, but I went ahead and did that for the mono white and GW versions if you want to check it out.
Courier Hawk is usually better than
Bay Falcon (unless you're really concerned about protection from white, in which case it's a good sideboard option). I've also tried a version that was WU with auras like
Psionic Gift and
Ocular Halo, which turned out to be pretty ineffective against removal. For what you're doing, I would recommend using 2-for-one spells like
Gallant Cavalry to ensure that you eventually meet the requirement for
Shared Discovery, which can be tough even with a creature-heavy deck.
