Training Grounds was originally introduced as only a Legacy format event. Between July and December 2018, Training Grounds ran on alternate days as alternating Legacy and Standard events.
The primary purpose of Training Grounds is to provide a place for players to test out deck ideas.
There is no limit to how many times the event's single node can be played.
