I am looking for a way too add items to airdrops. I looked at the past posts and saw orangemart ask about his infinite loot glitch. I have learnt how to cofig works from that and need some help to add some more.

I currently have a red card spawning inside it but would like to also add a blue card that is always spawned. (We are on a 3 grid map and dont have monuments)

This is my current config:

{
  "Refill Loot On Plugin Load": true,
  "Container Loot Save Command": "lootsave",
  "Container Refill Command": "lootrefill",

                    }
                ],
                "Amount": [

                ],
                "Chance": 1

            }
        ]

    }
  ],
  "Debug": false
}

If anyone could help it would be greatly appreciated.
Thanks a lot. :)
