The cost of each new style will depend on the cards rarity: Commons : 400 Gems (approximately $2.50, since 1,600 gems cost $9.99) Uncommons : 600 Gems (approximately $3.75) Rares : 1000 Gems (approximately $6.25) Mythic Rares : 1,200 Gems (approximately $7.50) Importantly, each new card style is only applicable to cards with the same art as as the card style
