Yu-Gi-Oh!: Spirit Caller Hints

Click on any random pack and add only ONE pack. Then click on the pack you want and press L and take away only one card (example press L to get 50 and get rid of one so I have 49) Go to another random pack and press R and it should say all your packs will only cost 150 DP

Buy the "Light into darkness" packs you might come across Merciless crossout. It is a normal spell card.(this is not a helpful glitch, just a secret) If you look at the description of the card, it will say "Select 1 monster on your side of the filed..."It does not say field, instead it says filed. It is just a spelling mistake, and also just a secret(not helpful)
