You buy a colored key to open the Command Card of the corresponding color, you equip the Command Code, you buy a Code Remover to remove the Command Code. These Removers are rare and apparently are going to be mostly Rare Prisms stuff. Be careful on what you equip, and on who and which card.

Aside from that, it's a percentage-based buff like "get 100 HP back when you attack with this card" or "deals 3% more critical damage with this card" etc.
