Cards that appeared in the "Heads I win Tails you Lose" secret lair are pulling both the cheapest version of the single faced card and the secret lair version. I found this issue with the following cards:
1 Okaun, Eye of Chaos
1 Zndrsplt, Eye of Wisdom
1 Krark's Thumb
1 Stitch in Time

I received this output:
1 Krark's Thumb $10.06
1 Krark's Thumb // Krark's Thumb $26.50
1 Okaun, Eye of Chaos $1.13
1 Okaun, Eye of Chaos // Okaun, Eye of Chaos $16.00
1 Stitch in Time $4.60
1 Stitch in Time // Stitch in Time $20.00
1 Zndrsplt, Eye of Wisdom $1.16
1 Zndrsplt, Eye of Wisdom // Zndrsplt, Eye of Wisdom $18.93

Particularly useful when you see that a card could not be found.

• figure out appropriate way to show decklist has populated with prices

Currently the entry point is one big js file. Would be better to modularize it a bit.

Most people want the cheapest legal printing of a card. Since gold bordered cards are not legal, it should be opt in to include them. Same with oversized cards.

Maybe switch to a 2 column design so the decklist with prices populates on the right side?
