They add more depth to the game giving it a long term goal.
I know most of us play in real life and would love to see Wagic The Homebew?! include more of those things.
I created a sliver deck before it wasn't that bad.
The deck that I am most proud of was my artifact deck.
Wow, was that deck good.
I had some really rare cards in it.
One of them said something like:
You can't lose the game and your opponents can't win the game.
If I can find the card I will post the real name of the card as well as all of the stats. I could even take a photo of it.
