When recycling multiple cards to the main deck (e.g., with Stacked Deck), do they need to be placed in a random order, and how is this randomization done in practice?

Ruling: When 2 or more cards are recycled to the main deck simultaneously, they must be placed on the bottom of the deck in a random order. Players typically present the cards face-down to their opponent who indicates which should go on top/bottom, or the opponent cuts them, to ensure randomness.

Sequence:

• Choose which cards are being recycled
• Place them face-down
• Opponent indicates order (e.g., pointing to which goes on top/bottom) or cuts them
• Cards go to bottom of main deck in the resulting random order

Nuances:

• Runes are NOT recycled in random order - they are recycled in order of your choosing
• The player recycling chooses WHICH cards are recycled, but not the ORDER when multiple cards are recycled simultaneously
• This is similar to the mulligan process where opponents help randomize card order
