I noticed that people have been starting "create a something game" so I wanted to start a create a keyword game. In this game you create the ability of a given keyword... so one person would say the next keyword is Aethercharge...
Aethercharge - exile a card. This permanent gets a charge counter for everytime a player plays a card of that type.
The permanent with Aethercharge would obviously use the charge counters for something. OK your turn
Next Keyword - Landscape
