212.6a A player may play a land card from his or her hand only during a main phase of his or her turn, and only when he or she has priority and the stack is empty. A land card isnt a spell card, and at no time is it a spell. When a player plays a land card, its simply put into play. The land
card doesnt go on the stack, so players cant respond to it with instants or activated abilities.
