As I understand it, jeseryn, only the large ones come with the green tint, and that's not all of them. I don't think you'd get one of them anyway - I think they're all older.
I think there was a thread recently (I'll look and come back if I find it) about someone having trouble with their new Thoth deck.
I'd personally steer clear of Amazon for this one, and go for eBay or trade for one on here. Heck, I've only ever done one reading with the Thoth and I have four of the buggers, so I doubt you'll have trouble getting one!
The small one is in the purple box. Also comes (as I understand) in the white "OTO" box, and I'd say that one would be more desirable, older, better printing.

ETA: Found it. Hope it helps.
