Activation is the process to turn a card into a tradable token. Tokens cost small amounts of ETH to create (known as ‘gas’), and the amount of ETH needed depends heavily on how busy Ethereum is at one given time.
We implemented activation to save users money, allowing them to tokenize individual cards they wish to trade or sell when the the cost of creating a token is low.
Cards do not need to be activated to be used in the game. The only time you will want to activate your cards is when you are looking to transfer it (such as when you are trading or selling it). You will always be able to activate your cards at any time in the future. We recommend waiting to activate your cards, as we will be implementing the ability for users to activate individual cards rather than decks.
