Location on card
A card’s rarity is found at the bottom of the card frame, slightly off-center to the right.
Rarity is a symbol to show the card’s artificial value or scarcity.
A card can be assigned one of six possible values for its Rarity. These are denoted by an uppercase R followed by a number without a space between them.
Such as: R1, R2, R3, R4, R5, R6.
Rarity-based Funding Costs
Some card types have Funding Costs that vary depending on the card's rarity.
The card types that follow this rule are:
The cost in each case equals to 2F plus half that card’s rarity level (rounded down). Given that formula, the minimum cost is 2F and the maximum is 5F, with some duplicates due to rounding.
R1 = 2F
R2 = 3F
R3 = 3F
R4 = 4F
R5 = 4F
R6 = 5F
Some cards have rules and effects that check a card’s rarity, so it is an active quality for cards from a gameplay standpoint.
