While this card is in your Graveyard, if your opponent uses "Mystical Space Typhoon" on your Set "Call of the Haunted", chain "Call of the Haunted" targeting this card to draw a card after "Mystical Space Typhoon" resolves.
By milling 3 cards with "Card Trooper", one can increase its ATK to 1900. This is enough to crash with an annoying "Thunder King Rai-Oh", which will lead to a +1 with the draw effect of "Trooper".
Use "Defense Draw" when your opponent attacks this card to draw an additional card and keep yourself from taking damage.
Use this card to quickly load monsters into the Graveyard for "Pot of Dichotomy". You can also use this card as one of your 3 Types if you don't play mostly Machine-Type monsters.
