Mulligans
General Mulligans
Keleseth is obviously the one you want out of the entire deck, mulligan ALL cards if you don't have it yet. If you have it already or missed it again, Kobold can rifle through to get it, or just play Flame Imp or Librarian for quick board presence. (if you have them)
A deck that takes the classic heal zoolock and adds Keleseth for extra punch against board clears and control.
