Yomi 2 deckboxes are designed to hold sleeved cards. The artwork on the sleeves is based on the cardback design of Yomi 2, but without the logo, so you can use them with any card game.
These sleeves are manufactured by UltraPro with the same process as their premium line of Eclipse sleeves.
Each pack has 100 sleeves. Here's how many packs you need for each pledge:
Novice Pledge: 1 pack
Challenger's Pledge: 5 packs (or 4 if you don't sleeve Lum's item deck)
Gameplay All-In Pledge: 9 packs (or 10 if you include stretch goal extras)
Other games: As many packs as you want!

Most cards in Yomi 2 have the same cardback so that you can use any gem cards with any character. That means a single design of sleeve makes sense for most cards. It's fine to use sleeves for ALL cards, but if you would like to get a few clear sleeves on your own for the cards that have different cardbacks, you'd need 116 clear sleeves for the Gameplay All-In Pledge: 10 stance cards for the character River, 12 item cards for Lum, 26 cards for Midori's Dragon deck, 23 cards for each character's main ability card, and 45 cards of stretch goals.
