Mulligans
General Mulligans
These are the two most useful cards to have on your opening hand. They are best supplemented by anything that discards, and a good 2-3 curve, since Zavas is never played on 2 and Jeklik is only a 4 drop if you've replicated her once already.
Making use of the new cards to see if Quest Discolock can have its ten minutes of fame before being relegated to wild to die forever.
Shriek, High Priestess Jeklik, Soulwarden, and Reckless Diretroll are the big newcomers, with Banana Buffoon playing a less big supporting role by giving you more cards as chaff for discard and utility if not discarded.
