yugioh gemini deck YU-GI-OH! - Summoner (SDWS-EN011) - Structure Warriors Strike - 1st Edition Yu-Gi-Oh! Legacy of the Duelist:

Its more than playable, even if it isnt a Craterhoof

For the Common Good Worst case scenario, For the Common Good is a card you use to recover after an opponent has decimated your life total

Even within the rules of fan-art I listed above: people buying it know theyre buying a proxy, a replicated card (at least, assuming its not someone trying to hock a proxy off as being authentic) the fact that it does use authentic artwork is tricky, and maybe the most grey of greys involved proxies dont interfere with the rights-holders from selling cards because, well, the rights-holders dont get ANY money from the secondary market to begin with

Some reverse holos are absolutely worth caring about
