I thought about making a mono black zombie deck about 2 or 3 months ago, and I have a basic idea of the deck, I just need to add more cards from older sets (like Relentless Dead into it to make it better, but my budget is about $15 and max $20. I most likely have some of the cards needed for the deck (such as Diregraf Colossus or Liliana's Mastery. Here is my deck so far:
As you can tell, most of these cards are from newer sets because that's all I have (I don't have about half of these cards but these are the cards I know the best).
