This gets a special card-frame - which is just a little bit bigger than a normal card, so that you can find it because it sticks out of your deck. Like the tombstone icon, but more functional :)

You mean, like the Eldraine special edition cards?

I like it. Unfortunately, it makes dredge decks, and especially Dread Return that much better (you can put four of these in your graveyard when you sacrifice an Verdant Catacombs.) But it isn't worth fretting over a broken deck from Modern.

I have a habit of making either 1) cool designs that I think or interesting, or 2) cards that would slot into decks I'm thinking about building. This was meant to go into a deck containing either or both of Thunderkin Awakener or Emry.

What does this do for Dread Return specifically?
