Can different parts of a Riftbound deck (main deck, rune deck, battlefields, champion, legend) use different colored sleeves?

Ruling: All cards within each deck type must use the same sleeves, but different deck types (main deck, rune deck, battlefields) can and should use different colored sleeves. Your Chosen Champion must use the same sleeves as your main deck since it can be shuffled into the deck. Your Legend can use different sleeves and can even be placed in a toploader.

Sequence:

• Main deck cards must all match sleeves
• Rune deck cards must all match sleeves (but can differ from main deck)
• Battlefield cards must all match sleeves (but can differ from main and rune decks)
• Chosen Champion must match main deck sleeves
• Legend can use different sleeves from everything else

Nuances:

• The Chosen Champion must match main deck sleeves because it can be shuffled into the deck (e.g., by Divine Judgement or recycling effects)
• All cards in the main deck must be the same language, but the Legend can be a different language
• Legends can be placed in toploaders
