Simulate opening booster packs from your custom set. Configure pack contents, open individual packs with animations, or run a full sealed event with deck building.
Booster Configuration
Enable booster packs in the set details panel under Draft Simulator. Configure how packs are assembled:
| Setting | Description |
|---|
|
| Enabled | Toggle booster packs on or off for this set |
| Pack Size | Total number of cards per booster (typically 15) |
| Slots | Define groups of cards with rarity distribution (e.g., 10 commons, 3 uncommons, 1 rare/mythic) |
| Holo Effect | Enable holographic/foil card effects in pack openings |
| Holo Chance | Percentage chance each card appears as holo (0-100%) |
| Pack Art | Cover image displayed on the booster pack wrapper |
Booster Slots
Each booster pack is made up of slots. A slot defines how many cards of a certain rarity are included. For example, a typical 15-card booster might have:
- 1 slot for 10 commons
- 1 slot for 3 uncommons
- 1 slot for 1 rare (with a chance of mythic, based on rarity weights)
- 1 slot for 1 common or uncommon (wildcard)
Each slot has a rarity distribution — weighted probabilities that determine which rarity is picked for each card in that slot. For example, a rare slot might have 80% rare and 20% mythic.
Tokens
Token cards are automatically excluded from booster packs.
Holo & Foil Effects
Enable holographic effects in the booster configuration. Set a holo chance percentage — each card in a pack has that probability of appearing with a foil/holo effect during the pack opening animation.
Opening a Single Pack
From the set page, click Open a Booster to open a single pack. The experience includes:
- Pack tearing animation to reveal cards
- Sequential card flip reveals
- Holo/foil effects on eligible cards
- Click any card for a fullscreen preview
- Open Another to generate a new pack
Sealed Simulator
From the set page, click Sealed Simulator to run a full sealed event:
- Open 6 booster packs sequentially (with pack animations)
- Cards accumulate into your sealed pool
- Build a deck by moving cards between your pool and deck — drag and drop cards to organise
- Click Playtest Deck to take your built deck into playtest mode
You can skip the pack reveal animation to add cards directly to your pool, or start a new sealed pool at any time. Your pool and deck state are saved in your browser so you can return to it later.
