## Problem Statement
Users cannot import an existing deck (already created in Flexslot) into a new Sideboard Guide. Currently, the only options are to import from text or create the deck from scratch, which is time-consuming and redundant when the deck already exists in the system.
## User Story
As a Flexslot user who has already created decks in the platform, I want to be able to select one of my existing decks when creating a Sideboard Guide, so that I don't have to re-enter my deck list manually.
## Current Workflow (Problematic)
  1. User has an existing deck in Flexslot
  2. User wants to create a Sideboard Guide for that deck
  3. User must either:
- Import the deck again via text (copy/paste from somewhere)
- Manually recreate the entire deck from scratch
  1. This duplicates effort and creates potential for inconsistencies
## Expected Workflow
  1. User starts creating a new Sideboard Guide
  2. User sees option to "Import from My Decks" or similar
  3. User selects from a list of their existing decks
  4. Deck is automatically populated into the Sideboard Guide
  5. User proceeds to add sideboard notes and matchup information
## Area
Sideboard Guides - Creation/Import flow
## Acceptance Criteria
  • [ ] Add "Import from My Decks" option in Sideboard Guide creation
  • [ ] Display user's existing decks in a searchable/filterable list
  • [ ] Allow selection of a deck to populate the guide
  • [ ] Properly link or copy deck data into the Sideboard Guide
  • [ ] Handle edge cases (empty deck list, deleted decks, etc.)
  • [ ] Consider whether to link to deck (synced updates) or copy (independent)
  • [ ] Update UI to make the import option discoverable
## Questions for Stakeholder
  1. Should the Sideboard Guide link to the original deck (changes sync) or copy it (independent)?
  2. Should users be able to import decks from other users (public decks)?
  3. What happens if the original deck is deleted after being imported?
