Not flooding the game with alternate art treatments was prudent, but the low pull rate of Enchanted cards was a detriment to the game
But if you run a card like Goblin Bombardment or Altar of Dementia, thats instant game over for your opponents
The miracling Reforge the Soul was heavily played and very cheap on the market after printing, but with just one reprinting since then it's slowly risen in value over time, and now the Commander deck bulk rare that was never printed in a Standard legal set is massively cheaper by a whole 6 bucks
While Magic Librarities has an archive of past links, shown below, it lacks a clear and easy way to document each new playtest card found, connected to an Alpha card in a systematic way
But otherwise, you should snap off those keeps and rely on the heart of the cards to deliver you
