Currently, there are two lackey generators in Warlock: EVIL Genius and EVIL Cable Rat. This means that you can produce six lackeys a game. That is more than enough to play EVIL Recruiter, which basically summons a 3/3 and a 5/5 for only three mana.
This could potentially come as early as turn three, which would be an incredibly aggressive and powerful move. Not that many decks are capable of dealing with a 5/5 minion so early.
So it looks like lackey-based Zoolock will thrive in this meta.
