This week's "Sketches" looks at the Onslaught enchantment, Aurification by Gary Ruddell.
1. Art Description
These are the instructions given to the artist:
Location: Daru Plains
Action: A beast changing into a statue of gold. Perhaps, we see other creatures that have been turned into gold in the background."
The card's playtest name was "Petrification," because the original concept was that the enchantment turned creatures into stone, but it was changed because changing things into gold was cooler.
This is the preliminary sketch of "Petrification" submitted by Ruddell.
3. Final Art
Here is a large version of the final piece.
Finally, here is the card as you'll see it in booster packs.
