What is training in Magic?
Training is a keyword from Innistrad: Crimson Vow. Whenever a creature with training attacks alongside a creature with greater power, it gets a +1/+1 counter, letting small creatures grow when they attack with larger ones.
Torens, Fist of the Angels creates a 1/1 token with training whenever you cast a creature spell, while Savior of Ollenbock exiles a creature each time it trains. Parish-Blade Trainee passes its counters on when it dies.
