Why Are MTGcardsmith Players Choosing Buy MTG Proxy?

The Zeta Set has players talking about Magic’s old school playtest roots, printed cards, and the fun of testing ideas before committing to expensive cardboard. That makes the current conversation around proxies especially interesting. I’ve been checking how MTGcardsmith fits the buy mtg proxy crowd when experimenting with Commander builds, alternate concepts, and casual testing. With prototype style cards suddenly part of Magic discussion again, this feels like a good moment to compare how players are approaching playable stand ins.
