Shovel Knight: Treasure Trove

Speaking to Chester either aboard the Glidewing or in one of the House of Joustus' will allow you to purchase 3 of his Cheat Cards. The cards are: Play 'Em All (allows you to play all three of the cards in your hand, costs 1450 gold), Gem Thief (all cards on a gem flip to become yours, costs 1350 gold), and Beeto Swap (change your opponent's hand to 3 weak cards, costs 1250 gold). Simply use all three of them at any time in the game and you will unlock the achievement. Keep in mind, nothing bad happens if you use these cards so feel free to use them as many times as you wish throughout the game. You can also buy multiples of the same card, but you must use all three of the different cards throughout the game in order to unlock the achievement.
