Oh no! Instead of replying to your post, Havelock, I accidently chose "edit" and wrote over your comment!
Havelock's comment was questioning why traps have to be hieroglyphs, since hieroglyphs are carved on stone, not creatures.
I think the set should definitely have booby traps of some sort to represent the tomb raiding association with Egypt in pop culture. Since the word "Trap" have been used before, we need another name. We could also redo the Traps from Zendikar, but I really like the type of traps that you set in advance and watch people walk into.
A separate concern is that I want hieroglyphs to be in the set somewhere, and I don't think something hyper-literal such as enchanting walls is that fun. I put these two motives together to propose hieroglyphs as traps.
Traps and Hieroglyphs don't absolutely need to be bound together, but I don't see why the flavor can't work either.
These can be magical glyphs. The art can show these blue, shining symbols of Eyes or Ankhs glowing on people's foreheads or shoulders. We can give these symbols their own names, like "Magoglyph" with names like "Magoglyph of Sight" "Magoglyph of Retribution."
I don't think it's a stretch, considering other fantasy concepts that have sprung from real-life mundane counterparts. There's things like staffs, potions, scrolls, which have real-life uses but do something different in fantasy. The best example for this case might be Runic magic, which appears in lots of fantasy games. Real runes are carved on wood or stone. But fantasy rune-mages can project runes or imbue runes onto other things to grant some magical effect. In the Kamigawa novels, the main character is this Kanji mage who pulls off all sorts of tricks by inscribing Kanji letters with magcial properties onto things, including himself or other people. The same thing could work with magical glyphs.
