Omnipresent Impostor

Changeling has always been a name-matching mechanic: a creature that is every creature type at once. This one takes the same premise and runs it through the rules stack in a direction the keyword never touched, declaring it has every card name. That single line reroutes an entire category of effects. Any search that specifies a card by name can find this instead, and because a library search that names a card almost always fetches exactly that card, the impostor becomes a legal target for tutors that were never meant to grab a 2/1. The bonus clause on the card formalizes the more mundane version: when you search for lands or creatures or anything by criteria, you may choose this as one of the cards you find, so a fetch effect doubles as a way to grab a body wherever it was headed. It is a joke design at the level of the flavor (a shapeshifter so total it answers to any name in the game) and a genuine combinatorial toy at the level of the rules, since "all card names" interacts with every corner of the game that keys off names: naming effects, sacrifice-a-card-named-X requirements, choosing counters. The 2/1 changeling body is almost incidental. What the card actually costs, mechanically, is a designer's willingness to let one creature satisfy a template that assumes names are unique, and most of the fun is finding where that assumption was load-bearing.
