"Architect of Deception" isn't an official Magic: The Gathering keyword or ability—it doesn't appear in the comprehensive rules or on any card I can verify. It may be a custom card, a Mythicwyrm-specific creation, a misremembered name, or a flavor title rather than a mechanic.
If you encountered this on a specific card, check the actual rules text printed in the card's text box, since that's what defines its function. The name above the type line is just flavor and has no gameplay meaning. If it's a homebrew or set-specific mechanic, you'll want to consult that source's rules document directly.
If you can share the card's actual oracle text or tell me which set or custom environment it's from, I can break down exactly how it works, the common rules traps, and its Commander applications.
