Xûr will appear to sell Gjallarhorn, Insurmountable Skullfort, Obsidian Mind, Mask of the Third Man, and a Exotic Primary Weapon Engram when in fact he's selling No Land Beyond, Ruin Wings, Sunbreakers, Lucky Raspberry, and an Exotic Gauntlet Engram; respectively. Put false Icons on all the items; make them look like the items everybody has been dying to get. I would laugh hysterically if they did that.
