We have no real idea how the deck algorithm works. However, we do "know" a few things. Certain cards always appear together. Bear Flute only occurs in decks with Ancient Bears, but Ancient Bears can appear by themselves. If you have two Bear Flutes, you will always have at least two Ancient Bears because every Bear Flute comes with an Ancient Bear. This leads me to believe that there are at least two 'mini combos' here... [Bear Flute + Ancient Bear] and [Ancient Bear]. There are currently ZERO decks with two or more Bear Flutes and 0-1 Ancient Bears.

There are a few other mini combos...

• The Four Horsemen always appear together.
• Time Traveler always appears with Help From a Future Self.
• Bear Flute always appears with an Ancient Bear.
• Faygin always appears with an Urchin.
• Niffle Queen always appears with a Niffle Ape.
• Routine Job always shows up as 2+. You never see a single Routine Job.

Anybody aware of any others?

I'm not 100% sure, but I assume Troop Call and Niffle Queen don't show up unless there's at least one Niffle Ape.

I've noticed that EVERY deck comes with a deck list. It doesn't combo with anything but it's a huge consistency.

Sorry I couldn't resist.

Back on topic would Master of 1, Master of 2 and Master of 3 fit in this category?

Sanctum's oath of poverty should always come with artifacts so that might qualify even if it's a bit more generic.

Based on the data on the decks from https://keyforge-compendium.com

Routine Job almost always appears in even numbers in decks.

Decks with X Routine Jobs:
1 0
2 10866
3 21
4 109
5+ 0

Niffle Queen always comes with at least 2 Niffle Apes.

Edit: It seems that keyforge compendium's search doesn't work quite properly. Searching for decks with 1 Niffle Queen and 1 Niffle Ape returns 2 decks, neither of which satisfies this condition.

X Niffle Apes in a deck with 1 Niffle Queen
1 0 decks (search erraneously returned 2)
2 17855 decks

Faygin actually seems to come with at least 2 Urchins. Can't find any decks that would only have 1.

X Urchins in a deck with 1 Faygin:
1 0 decks
2 7673 decks
3 2893 decks

Troop Call seems to always come with at least one Niffle Ape.

X Niffle Apes in a deck with 1 Troop Call:
1 17036
2 7877
3 3797
4 663
5+ 97

And as mentioned previously, Power of X's are an anti-combo, only appearing one at a time as far as I know.

Oh man, I forgot the deck list!

Master of 1, 2 and 3 don't necessarily appear together. I'll have to look into Oath of Poverty, but that's a tough one to decide because most decks have at least one artifact anyways.

Oath of Poverty does not require artifacts.

Good stuff. I was searching on my phone since I'm work blocked. I'd love to have a giant data dump so I could run the analysis myself at home.
