A card with the requirement keyword can’t be played unless each resource of the specified type, depicted in brackets, is spent while paying for that card’s cost.
- You can use wild resource to play for the required one.
- If an effect states you can play a card without paying it’s resource cost, you can’t play a card that has the requirement keyword.
- Cost reduction cards can’t remove the requirement.
- Even if the cost of the card is 0, you still need to pay the requirement cost.
