Scryline

Scryline is a desktop overlay built with Electron and React that sits on top of MTG Arena during a draft. It watches the game's log file to detect packs and picks automatically, pulls card identity from Scryfall and win-rate stats from 17lands, and layers in Claude-powered coaching to help with pick and deck-building decisions in real time. The card evaluation underneath it is custom: cards score out of 100 on win rate in hand, impact-when-drawn against their mana-cost peers, and how far they beat their colour pair, then grade S through U. A second pass re-scores each pack against the pool you hold, sliding from raw power early to filling curve and removal gaps by pack three.
