It's not the judge promo - it's a regular, non-foil Lorwyn Gaddock Teeg, but it's got a green ink stamp on one corner of the text box. The card came from a draft event at a Professional event, where stamps are added to prevent cheating. Otherwise it's NM, so I'd value it around an LP-NM copy.

And yes, it is certainly tournament-legal.

How does something like this look?

My:
1 x Gaddock Teeg (GP Stamped) 35ish
1 x Concealed Courtyard 4.62
Total: 39.62

Your:
2 x Windswept Heath 26.16
2 x Spirebluff Canal 14.92
Tota: 41.08

I should be able to toss in a couple of foil basics or something similar to make up the difference. Let me know how this sounds!

Your:
1 CON Noble Hierarch LP
1 Inventors Fair
1 River's Rebuke

If it helps I could add an Inspiring Vantage to the trade I proposed (plus some foil basics), but otherwise I'm having a hard time making values line up...

I'm interested in your:

2x Ghalta Primal Hunger (promo)
1x History of Benalia

Please take a look at my list to see if there is anything you can use.

3x windswept heath
polluted delta
inkmoth nexus
breeding pool

any deal using any combination of those cards would work ..... lmk thanks
