whats a good cheap craftsman deck for farming adventure bosses?

I don't know about cheap, but I use queen of avalonia, ramen, and jorus.

For cards I use.

3 Hot Noodles
3 Good Jorusien
3 Odds and Ends (helps to draw the cards)
3 cursed spell books
3 cup of lifes
1 crown of the border
1 skyward boots (increases her level faster so triumph does more damage)
1 clan signet ring (good for extra attack/spirit and just nice so you don't deck out)
1 triumph (not needed but speeds things up greatly and is good for high defense bosses and it recycles itself)
1 sacred avalonian blade (not needed but can speed things up)

and a shield of some sort (I use light and shadow shield but not everyone has that, so avalonian shield works to)

The most expensive key cards are the cursed spell books, cup of life, and the queen of avalonia.

But if played right you can get queen with stats like.

10-13 spirit (she heals for every point of spirit)
4-6 defense

Eventually you can be doing 20+ damage per hit with triumph.

why the cursed book?

the cursed book gives +2 spirit so the 3 dmg is neglible, also with jourisen the dmg is less and then its just a +2 spirit item, and with 3 of them it is a giant healing bonus where only the first one does dmg to yourself.
but if you can't afford them you might have valentynes diadem that gives +2 spirit (from valentines event)
(hrimnirs crown from recent event)
(clan signet ring)
if you have gold medal from olympus it is also a nice add.
(if not eredan saga vol. 1 can take its place the +1 stats each turn really helps out if you got bad draws)
but most of these items are not needed if you can afford the cursed books.
(gold medal and valentynes crown is still neat tho)

I personally use 3 triumph with that +1 spirit +1 defense heals 1 hit point self recycling card so i got 4 cards that recycle.

I personally prefer over for the former's chaining ability and healing with . Galeine can also utilize to discard opponents' items.

The following may also be added if you have them:
Valentyne's Armor and diadem
Neferthot
Gold Medal (not really reliable)
Health Potion
Zarazam's Eye against mages.

The Queen can easily defeat dark tower freaks such as Saphyra, Skunk-man, Jorus, Malwein, and the Sap Boss.

I'm using runic craftmen and i don't find the deck has much difference from queen deck , it's even cheaper
