Hmmm I was thinking about something very complex, but then I stumbled upon something simple that just works with the current rules?

You play Necromancer into Treasure Hunter and gain 2000 silvers.

why 2000, you ask?

Only actions from Nocturne allowed.

Also you can't play Necromancer into anything because that's two cards.

Hmm, ok. It's one card but it is two plays yes.

So here is without breaking that rule:

[hand: 3x cultist, catacombs, copper]

play fool

discard copper

gain cemetery(1)

trash 3x cultist, catacombs

draw 7x cultist, 2x catacombs

gain cemetery(2)

[hand: 7x cultist, 2x catacombs]

trash 3x cultist, catacombs

draw 7x catacombs, 2x feodum

gain cemetery(3)

[hand: 4x cultist, 8x catacombs, 2x feodum]

trash 3x cultist, catacombs

draw 6x feodum, 3x squire

gain cemetery(4)

[hand: 1x cultist, 7x catacombs, 8x feodum, 3x squire]

trash 1x cultist, 3x catacombs

draw hunting grounds, watchtower, trader

gain 3x cemetery(5, 6, 7)

[hand: 4x catacombs, 8x feodum, 1x squire, Trader]

12 trashes + 3 (trash catacombs -> cemetery(8 )) = 15 trashes

trash 3 catacombs (death cart, 3 each), 8 feodum (3 each) and 3 squires (skulk, 2 each)

this is 32.

Now we get to trash the hunting grounds and with the fore mentioned inheritance-ferry trick we can gain 2 more for every estate.

I think we're at 48 now?

oh and you can exchange the cemeteries for free so 56.

And then we still get to resolve the other two boons from the fool. Probably can get a few more there.
