"Translocation Protocols" isn't an official Magic: The Gathering keyword or ability—it doesn't appear in the comprehensive rules or on any printed card. It sounds like flavorful homebrew or a misremembered name, possibly confused with real mechanics like phasing, blinking (exile and return), or flicker effects that "translocate" permanents.
If you encountered this on a custom card or a non-official set, ask the card's creator or your playgroup for its exact rules text, since unofficial mechanics define their own behavior. In sanctioned Commander, you'll want to map it to an existing template—does it exile and return creatures, phase them out, or move them between zones?
For real blink-style effects, remember the common nuance: returning a creature is a brand-new object, so it loses counters, auras, and "until end of turn" effects, and re-triggers enter-the-battlefield abilities.
