Bern Ayotte developed end-to-end KyberDecks deck import functionality for the SWU-Karabast/forceteki-client repository, expanding available deck sources and streamlining the user testing workflow. He integrated KyberDecks as a new source by updating the DeckSource enum and related constants, and implemented URL-based JSON retrieval using TypeScript and API integration techniques. Bern ensured compatibility with existing DeckJSON interfaces, including support for specialized fields like 'secondleader' in Twin Suns. His work included safe parsing in route.ts and integration with a Supabase Edge Function, resulting in a robust, maintainable feature that improved developer velocity and reduced manual steps in deck testing.
