# Deck and Side Deck

## 🃏🔧Deck Building

1. Each deck must contain at least 60 cards, plus 1 starter Starlight.
2. You may include up to 4 copies of any individual card in your deck, except for your starter Starlight, which follows the unique copy rule.
3. Your starter Starlight must be Rank 1.

## Starter Rules

### Unique copy rule

The starter Starlight must be Rank 1 and a unique copy. This does not prevent you from including other Starlights with the same name in your deck, as long as they are different versions from the starter.

### Astral Rule

* When a starter Starlight is placed into its owner's deck or discard pile, the owner may choose to either leave it there or send it to the Astral.
* If the Starlight is sent to the Astral, it returns to the owner's hand at the start of their second turn after being placed there.
* If the Starlight is vanished, it is automatically sent to the Astral and returns to the owner's hand at the beginning of their second turn following its placement.

## 🧳 Side Deck Rules

\- You may include up to 15 cards in your side deck to swap with cards in your main deck between games, just like a standard sideboarding system.  \
\- Additionally, you may include up to 15 extra cards designated as special side deck cards, such as Night Runner Cards or Constellation Cards.
