Gandalf the Whites standard card shows him illuminating his hand with magic during the battle at Minas Tirith, while his Ring Showcase card appears to depict his transformation from Gandalf the Grey to Gandalf the White after his battle with Durins Bane, drawing from Tolkiens description: There I lay staring upward, while the stars wheeled over, and each day was as long as a life-age of the earth.
