Most cards that want a lot of draw power focus on trying to get +1s and thinning out the deck. Pretty much anything that can let you search through your deck will help. Things like Gold Sarcophagus, Reinforcement of the Army, and Deep Sea Diva help. Especially because Diva can help synchro summon. Of course, combos like Dark World Dealings, Card Destruction, Morphing jar, and Destiny Hero - Malicious, are always good.

You could run a powerful fairy deck with Tethys goddess of light and Airknight Parshath/Neo-Parshath, the Sky Paladin as a combo. And with fairy searchers like Shining Angel and Nova Summoner, it shouldn't be that hard of a deck to thin out, either. And with cards like Solidarity, it'd also be pretty powerful if you stick to only fairies. And with tuners like Counselor Lily, that might be even more powerful.
Just suggestions.
And okay, Pharmacist.
