It can be a surprise flying blocker that draws you a card, or it can be all that plus a deathtouch creature that takes out whatever it blocks

Legacy and Vintage are great formats, and most players would be perfectly fine with playing against opponents with some number of proxies in their decks if it meant they could play their favorite format on a regular basis

Gastly cards range from mischievous to iconic, with valuable prints like Neo Destiny and E-Reader

There are special limits for cards like Ace Spec or Prism Star
