What is Chain Link?
Chainis a “pile” that determines the resolution order of cards and effects activated during a duel. Cards and effects only go in a Chain if they are activated.
Chain Link(Chain Link), the first activation being Chain Link 1 or “Chain Link 1”. Players must follow fast effect timing rules when adding effects to the chain. If neither player responds to the most recent Chain Link, the Chain resolves, with the Chain Links resolving in the opposite order of their activation. Cards and effects can only be added to a Chain while it is being built, and once a Chain begins to resolve, cards and effects cannot be activated until the entire Chain is resolved.
Starting a chainThe turn player has the right to start a Chain at any time during their turn. However, this right will pass to the opponent on some occasions: > When the player on the turn doesn't want to take any action while the game state is closed; > When the player on the turn wants to move to the next Stage/Phase of the duel; > When the opponent has a Flip, Trigger Effect, or Trigger-like effect that meets its activation time.
Building a ChainThe card or effect that started the Chain corresponds to Chain Link 1 or Chain Link 1. The next one will be Chain Link 2, then Chain Link 3 and so on, with each number corresponding to when it was activated in relation to the other Chain Links. Cards and effects can only be activated as Chain Link 2 or higher if they have a spell speed equal to or greater than the previous Chain Link. Spell Speed 1 effects cannot be activated at Chain Link 2 or higher, except for Trigger and Trigger-like effects if triggered simultaneously; in this case, they must be Chained first before any player has the opportunity to activate quick effects. New Chain Links can be activated in response to either the most recent activation (the immediately preceding Chain Link) or the card or effect to which Chain Link 1 is responding. After putting all spell speed 1 effects into the Chain, or after any quick effect activation, the player who hasn't added the current Chain Link has the right to add a new one or pass it to their opponent. If the opponent doesn't add effects to the Chain, the Chain is complete. Cards and effects cannot be resolved until the Chain resolution ends.
Resolving a ChainOnce both players have decided not to add any more effects to the Chain, the Chain is complete. Thus, the Chain is resolved, starting from the Chain's most recent Chain Link. That is, it resolves backwards. Cards and effects cannot be activated while a Chain is resolving. Once the entire Chain is resolved, if any of the cards have not yet been moved to another location, they will be sent to the Graveyard. This action occurs simultaneously with the last part of the last resolved Chain Link effect's resolution.
ExampleChain Link 1: Player 1 activates Raigeki. Chain Link 2: Player 2 activates Anti Raigeki in response to "Raigeki". Chain Link 3: Player 1 activates Solemn Judgment in response to “Anti Raigeki” by paying half their life.
What is SEGOC?
Simultaneous Effects Go On Chain, which is a process used to handle multiple
Trigger-Likeeffects that reach their activation time at the same time. If this occurs, all activated Trigger and Trigger-Like effects are placed in a Chain.
Activation orderTrigger and Trigger-Like Effects when activated at the same time, must follow the following order in the construction of the Chain: > Mandatory effects of the turn player; > Mandatory effects from the other player; > Optional turn player effects; > Optional effects from the other player. If a player has two effects in the same category (two mandatory effects or two optional effects), then that player decides the order in which to activate them, but always respecting the order shown above.
Example 1Player 1 controls Babycerasaurus and Overtex Qoatlus. While Player 2 controls Sangan and Peten the Dark Clown. Player 1 activates Dark Hole to destroy all these monsters simultaneously, then the effects of the 4 monsters reach their activation times at the same time, and thus, the Chain will be built as follows: Chain Link 1: Babycerasaurus, which is the only mandatory player effect for the turn.
Example 2Player 1 controls Dharc the Dark Charmer, Gloomy and declares an attack on Lyna the Light Charmer, Lustrous on opponent's control. After the damage calculation both are destroyed, the Chain will be built as follows: Chain Link 1: Dharc the Dark Charmer, Gloomy, which is the turn player's only optional effect if they choose to activate it.
Example 3Player 1 controls Sangan and Witch of the Black Forest. While Player 2 controls Sangan and Peten the Dark Clown. Player 1 activates Dark Hole to destroy all these monsters simultaneously, then the effects of the 4 monsters reach their activation times at the same time, and thus, the Chain will be built as follows: Chain Link 1 and Chain Link 2: The turn player has 2 mandatory effects of Sangan and Witch of the Black Forest. These effects will be Chain Links 1 and 2, the turn player decides the order in which they will activate.
SEGOC LimitationEach player can only activate 1 Trigger effect of a monster that can Special Summon itself from their hand by Chain.
Example 1Even if the player has Battle Fader and Ogre of the Scarlet Sorrow in hand when their opponent declares their second direct attack during a given turn, they can only activate the effect of one of these cards.
Example 2When a face-up Beast-Type monster the player controls is destroyed and sent to the Graveyard, even if there are multiple copies of Green Baboon, Defender of the Forest in your hand and/or Graveyard, they can only activate the effect of one of them. This applies even if all copies are in the Graveyard.
Chain BlockingThe Chain rule only allows the last Chain Link to be answered, while the “SEGOC” allows players to choose the order of activation of the effect, as they have the same priority. The “Chain blocking” consists of organizing your Chain Links in order to “protect” their most important effects, placing them in the previous Chain Links and the less important or more difficult to combat as the last one.
ExamplePlayer 1 controls Flame Bufferlo while Player 2 has Ash Blossom & Joyous Spring in hand. Player 1 decides to use Flame Bufferlo as material for Link Summoning Salamangreat Balelynx, at which point there are two optional effects that can be activated and to “PLAY around” a possible Ash Blossom & Joyous Spring in the opponent's hand, the player must place its most important effect as Chain Link 1 and the least important as Chain Link 2.
