Could you build this?
Partial The draft-trainer UI and tier lists are buildable, but live win-chance predictions need a model trained on large volumes of match data and Riot API access that complies with its terms. The public scoring of predictions also needs reliable data pipelines.
What it would actually take: Use the Riot Games API and match-history data to train a draft-state win-probability model, then serve it in a web or overlay client with low-latency updates during champ select. The hard parts are building a well-calibrated model from a large labeled dataset and keeping the live pipeline accurate and fast. Riot API production approval and data storage are also needed.
