Can I use different colored sleeves for my Legend, main deck, Runes, and Tokens?

Ruling: Yes, you can use different colored sleeves for different deck types (Legend, main deck, Runes, Tokens), since these cards have different colored backings anyway.

Nuances:

• All sleeves within each individual deck type must be identical to each other
• All cards within a deck must be placed in sleeves in the same manner
• Cards in decks must have the same number of layers and be the same orientation at all times
