In Buddyfight, chains do not exist in the same capacity as in, for example, Yu-Gi-Oh!. A Buddyfight "chain" refers to the rule that each player can only have one ACT or AUTO effect in play to be resolved at any one time.

e.g. A player calls Schwarz "SD", and Schwarz "SD"'s on-call skill becomes the only standby effect. The player must declare they play Schwarz "SD"'s on-call skill, whether they intend to discard a card during resolution or not. The opponent may then respond with Counter. After the opponent chooses whether or not to respond, each player will have had the opportunity to have one active ACT or AUTO effect in play each, so neither player can play further ACT or AUTO effects until this chain resolves.

In particular, AUTO effects interact very differently to how they would in Yu-Gi-Oh!. The scenario is: a player has First Darkhero Hideout set on the field, Shadow Hero, Schwarz (or Schwarz "SD") and Noble of Darkness, Killnight in hand.

For Shadow Hero, Schwarz:

A1 - The player declares they call or buddy call "Shadow Hero, Schwarz", and they pay the call cost of 1 gauge and discarding 1 card; the card discarded is Killnight.

A2 - The opponent may respond with Counter (unless this is during a battle and they have already used Counter during this battle), but does not respond with a card/effect to nullify the call.

A3 - When the call succeeds, if this is a buddy call, the player gains 1 life with buddy gift.

A4 - Since Killnight has been put in the drop zone from the hand, the activation condition for its AUTO skill is met, so it goes on standby. At the same time, since Schwarz has entered the field, the activation condition for its on-call AUTO skill has been met, so it goes on standby. Also at the same time, since Schwarz is a Darkhero that has entered the field, the activation condition for First Darkhero Hideout's AUTO effect has been met, so it does on standby.

Since one or more card have their conditions met at the same time, first, the turn player can choose to resolve any effect on standby in their "pool" in any order, but only one at a time, until they have used or (if not mandatory) chosen not to use each effect.

An 1 - The player chooses one of their standby effects to play.

An 2 - The opponent may respond with Counter (unless this is during a battle and they have already used Counter during this battle), but chooses not to.

An 3 - The player resolves their effect.

Repeat An 1-3 for all the turn player's standby effects

Ax - After the turn player has dealt with all their standby effects, the non-turn player can then do the same.

In the case of Schwarz "SD", A1-3 are the same, however, as Killnight is not discarded until the resolution of Schwarz "SD"'s skill, it will not currently be on standby during A4. Assuming the player chooses to use Schwarz "SD" at any point during steps An, Killnight will become standby and will be added to the player's "pool" of standby effects, at which point it is treated no differently to any other currently standby effects that could be chosen to be played in step An 1. Similarly, if the non-turn player's effect would become standby during the resolution of the turn player's standby effects, it is added to their "pool".

So you could play Schwarz "SD" first, then Killnight would become standby and Hideout would still be standby, so you can play those in either order, one at a time. Or you could resolve Hideout first (perhaps drawing into Killnight), then resolve Schwarz "SD", which would then cause Killnight to become standby, so you could use it next before your opponent proceeds with playing their standby effects.

Note: "Pool" is a non-official term.
