Sideboarder

Sideboarder is a mobile + web app (traditional + AI) that helps competitive TCG players build and maintain sideboard plans for real matchups, not vague “meta” advice. You pick your deck, format, and expected opponents, then the app generates a structured sideboard guide: what to bring in/out, play/draw differences, and key mulligan notes. The AI is used to draft an initial plan from public decklists, tournament results, and your own notes; you then lock it into a versioned “guide” you can trust. During events, you can quickly pull up the exact plan, track what you actually faced, and rate whether the plan worked. Over time, Sideboarder learns your local meta and suggests small, testable tweaks rather than constant churn. It’s designed to be fast between rounds, offline-friendly, and focused on practical execution.
