## 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.)
  • [ ] Create a full copy, dont just link an existing deck to a new sideboard guide
  • [ ] Update UI to make the import option discoverable
## Questions for Stakeholder
  1. Should users be able to import decks from other users (public decks)?
Answer: only from the deck detail page if they have access to the deck -- using a button or dropdown menu item like "Create new SB with this deck"
  1. What happens if the original deck is deleted after being imported?
answer: nothing, this process is completely decoupled from the original deck.
