I have mostly been following this strategy:
Stay away from green- this is based on games me and my brother failed at. green seems to have drops that are simply too slow, good 5/6 drops mostly. also a 1 turn mana screw can lose games in thia format and a higher curve raises the chances of this. also some cards in it are only good if it's your heavey main colour and as it is bad it soudln't be.
take note of curve though look for low costed creature- usually I would look for about 4 3 two drops -5 4 three drop 43- four drops 2 five drops and a high cosr cost bomb or too two but in zendikar draft i want at least 6 one/two costed creatures that are aggressive so they have 2 power or something similar, and get the rest of the 4 three drops as low 3 four drops and a high costed but powerful as I canbomb or two.
notice decent allies in your colours- at first i didn't like allies but now I see that most of them are decent in aggro, the red and black once especially. I woudn't splash for an ally or pick one over a decent removale but i still would try to collect many in a draft that seems to pass them along as late picks.
Also I am not sure but some people say you should be playing 18 lands in this set, I guess for landfall and to make sure you don't get that critical land too late, but I hate drawing too many of them as well...
the best draft decks I've drafted have been: RB allies, WU Flying aggro, WB/WR/RB low costed aggro. I have drafted 5 times and drafted online about 12 times I think, though the shuffler on online has been very mean to me lately...
