Recycling and burning out

Two actions move cards around your decks. Recycling puts cards on the bottom of a deck. Burning out is what happens when you ask your Main Deck for more cards than it has. They meet when a burn out recycles your trash.

Worked example, recycling. You play Disposal Order and choose the mode "Choose up to 3 cards from opponents' trashes. Their owners recycle them." Each player recycles cards to their own decks, whichever player is instructed (rule 417.1.c), so the three cards go to the bottom of your opponent's Main Deck, not yours. Because they arrive together they are placed in a random order (rule 417.5). Main Deck cards recycle to the Main Deck and runes to the Rune Deck (rule 417.1.a and rule 417.1.b), and a token recycles to the deck of its type and then ceases to exist (rule 185.2.e and rule 186.1).

Worked example, burning out. Your Main Deck has 2 cards and you hold Shadow Temple, "When you hold here, Burn 3". You put 2 cards into your trash, which is as many as you can, then you burn out: your trash, including those 2 cards, is recycled into your Main Deck, an opponent of your choice gains 1 point, and you put the remaining 1 card into your trash (rule 432.1.b and rule 432.2).

Recycling details. When recycling is a cost, the action must be able to be completed for the cost to be paid (rule 417.3). When it is part of an effect, the player recycles as many cards as possible (rule 417.4). That is why rule 417.4 never rescues a cost. "Recycle X from [zone]" means X cards of that player's choice and does not target (rule 417.6). Two or more cards recycled to the Main Deck together go on the bottom in a random order, and to the Rune Deck in the order the owner chooses (rule 417.5 and rule 417.5.a). At a tournament, when two or more cards are recycled to the Main Deck in a single action, the shuffling procedures are followed for that group first (TR 421.8). The same applies when a Burn Out recycles the trash (rule 432.2.b).

Burn Out details. A player burns out when they try to move cards from their Main Deck to another zone in excess of the cards remaining (rule 432.1). When drawing, they draw as many as possible, burn out, then draw the rest (rule 432.1.a). Putting cards into any other zone, such as the trash, works the same way (rule 432.1.b). Looking at or revealing more cards than the deck holds does not cause a burn out, and further instructions that need cards that were not there are negated (rule 432.1.c and rule 432.1.c.1). Burning out is a replacement effect (rule 432.5). If the Main Deck stays empty, usually because the trash is empty too, trying the action again causes another burn out (rule 432.3). Points gained after the first burn out in that sequence can't be replaced or prevented (rule 432.3.b), and one that brings an opponent to the Victory Score with more points than anyone wins the game immediately, without waiting for a cleanup (rule 432.3.c and rule 432.3.c.1).

Common mistake. "My opponent's Disposal Order puts my cards in their deck." No: owners always recycle their own cards.
