403.1. Recycling cards is the action in which a player takes one or more cards from a specific zone and then puts it on the bottom of the corresponding deck.

403.2. This is a Limited Action.

403.3. When Recycling is listed as a Cost , the action must be able to be completed for the cost to be paid. Example: Vi, Destructive has the ability "Recycle 1 from your trash: Give me +1 [M] this turn." Each time a player activates the ability, they must recycle 1 card from their trash to pay its cost. If they have no cards in their trash, they can't activate the ability, because they can't pay its cost.

403.4. When Recycling is part of an effect, a player must Recycle as many cards as possible from the specified zone or zones.

403.5. If 2 or more cards are Recycled to the Main Deck simultaneously, they are placed on the bottom of that deck in a random order. Example: Garbage Grabber has the ability "Recycle 3 from your trash, [1], [E]: Draw " To pay the cost of activating this ability, its controller chooses 3 cards from their trash and places them on the bottom of their Main Deck in a random order.

403.6. This action, when instructed, is sometimes formatted as " Recycle X from [Zone]." That means to take X cards of the instructed player's choice from the relevant zone and recycle them. Example: Dr. Mundo, Expert has the ability "At the start of your Beginning Phase, recycle 3 from your trash." As that ability resolves, its controller recycles 3 cards from their trash. If there are fewer than 3 cards in that player's trash, they recycle as many as they can.
