When you recycle 2 cards during a mulligan, do you shuffle them together?

Ruling: When 2 or more cards are recycled to the Main Deck simultaneously (such as during a mulligan), they are placed on the bottom of the deck in a random order. You shuffle only the recycled cards together, not the entire deck.

Sequence:

• Set aside cards for mulligan
• Recycle the set-aside cards
• Randomize only those recycled cards together on the bottom of the deck

Nuances:

• The opponent can also shuffle your recycled cards
• Only the recycled cards are shuffled together, not the entire deck
