so
I forgot to put mulligans into primer:

outlander dh
ping priest
landmines warrior
weapon druid- rain/surge

token dh
warlock 
diablo 3
recruit pal
token druid- perpetual/chain/lightning storm/coin+volcano

rush warrior
shaman - missiles, hand, frostbite

diablo 6
resurrect paladin
hunter- missiles, snowball, shock

notetaker is kept with the left most card in the guide
fireheart is kept always

that section will be upgraded as I play more duels next season.
