I would second the recommendation to move off Heroku. They're essentially the smallest scale version of vendor lock-in out there nowadays, especially considering they're no longer free. An open-sourced codedump will survive best if people (which effectively means "average technically-minded MTG player" in this case) can run it wherever they're most comfortable - which will almost certainly be something that smells like a VPS. Mayyybe a container.
