Judges of Faith
Evangelism is the spreading of religion, generally Christian but now just a coverall for all religions. So it could be relevant if church groups wanted to sponsor/encourage MtG in the community etc.
Discipleship is the same, as far as I know, you become a Christian “disciple”, spreading the faith.
Overall it wouldn't be a bad idea, especially in terms of finding places to pray or attend your faith's gatherings, when at large events, and for local groups to form if there is an audience for it.
Are there currently provisions in place at larger events for Salah, the 5-a-day Islamic prayers? I.e. 5 minutes off a match or a small area with mats. I have seen them, rarely, in some cities, but not at an event, although I haven't been looking. Things like this would help make MtG events more inclusive to people from all walks of life.
