Hi,
I included the elixirs because I see two significant benefits :
1- shuffling key sorceries like Hymn,
Sinkhole and
Smallpox back into your deck increasing your amount of copies/effects and
2- adding a significant life gain per pop, which the deck can certainly use.
How effective they'll be remains to be seen though but I like the fact they can be ritualed out to be used and you get the ritual back as well.
There may be more effective cards in those slots however. Which were you thinking of ?
