A whole fresh army answers your call: a new queen, two rooks, two bishops and two knights appear on empty squares in your half, and every remaining empty square in your half fills with a new pawn. It spills onto the rest of the board only if your half runs out of room.
You draft Grand Army in Buff mode. Activated: you choose when to use it, and using it is your move for that turn.
As a pieces card, it summons, revives, promotes, or converts a piece.
“Rank upon rank upon rank, out of nowhere.”
