The premium group is only 2 keys or $5 USD in skins (maximum 3 skins) for a lifetime membership in the group. To join, please send a trade offer to:

I sometimes post predictions on the group discussion page, but most predictions will be on the spreadsheet. After sending a trade offer, I will accept it as soon as I see it and invite you to the premium group where there are further instructions on how to join my spreadsheet. See you there! :)
