This achievement requires you to activate the expansion "The Reaper" and then choose to play as the Samurai character. It's best to play with another, second character you also control("Local Player"), and they need to be the Ninja character.
Run around with both characters until one of them eventually draws the Golden Statue object card from the deck. Let the Ninja pick it up - don't pick it up with the Samurai character. Now that your Ninja has the Golden Statue, battle them with the Samurai character.
When the Samurai character wins the battle, take the Golden Statue from the Ninja and the achievement will unlock.
