Attach — Riftbound Rules

Section 434 — 16 rules

434.1.
Attaching is the act of linking two cards on the board together to combine their effects in some way. This causes one or more cards to become Attached and at least one card to become a Top-Most Card. See rule 716. Attachment for more information.
434.1.a.
Attaching affects two cards at once.
434.1.a.1.
One card will be designated as the one being Attached, and thus become Attached. The other will become the Top-Most Card.
434.1.b.
This is represented by physically laying the Top-Most card on top of the other or others such that all Effect Texts and Might Bonuses are showing, but nothing else from the card or cards Attached.
434.1.b.1.
In the situation where there is more than one card attached to the Top-Most card, they should be stacked in such a way that all Effect Text boxes and Might Bonuses are readable. The order of the Attached cards has no bearing on the application of effects.
434.1.c.
The Top-Most card has all Effect Text of all cards Attached to it appended to its Rules Text.
434.1.d.
The Top-Most Card has its Might modulated by the Might Bonus of all cards Attached to it.
434.1.e.
Attaching one or more cards will cause those cards’ Rules Text to become Inactive for as long as they remain Attached. See rule 716. Attachment for more information.
434.1.f.
Attaching a card to a new Top-Most Card will cause it to Detach from the card to which it is currently Attached.
434.1.g.
Attaching a card to its current Top-Most Card will not have any effect.
434.1.h.
If a Game Effect instructs a player to Attach a card to its current Top-Most Card, nothing additional happens.
434.2.
Attaching is a Limited Action.
434.2.a.
Players may only Attach cards when directed to by Game Effects.
434.3.
Attaching cards does not inherently choose or specify a target. However, Game Effects that Attach cards may do so.
434.4.
When a card Attaches to a card, its location becomes the same as the new Top-Most Card.
434.4.a.
This is not a Move.

Does Edge of Night's auto-attach ability work?

Unattended gear at battlefields are recalled, causing Edge of Night to return to your base while its ability is on the chain. Errata changes the wording so it can still find the unit you chose at the battlefield.

Aphelios, Exalted has an ability that triggers when I attach an Equipment to him and tells me to "choose one that hasn't been chosen this turn." If I attach Svellsongur to him, does he have the second copy of his ability in time for both to trigger? And do I have to choose different options?

He does have the second copy of his ability in time, and it will trigger. The restriction applies separately to each instance of his ability, so you could choose the same option for both.
