NFT cooldown is the time during which you
  cannot use an NFT because it was used too recently by another player.
  - 
    Some cards impose an NFT cooldown, meaning that once you use it, another player may
    not take advantage of its powers until 48 hours have passed.
  
- 
    If you are the last person to use an NFT, the cooldown does not apply to you.
  
- 
    The NFT cooldown does not prevent you from sending a card to another player.
  
- 
    When you send to someone a card that is on cooldown, it will show up in their inventory with an hourglass icon
     underneath.
    They can keep the card, but cannot make use of it until the cooldown is over.
