The card states:
Loxodon Smiter can't be countered. If a spell or ability an opponent controls causes you to discard Loxodon Smiter, put it onto the battlefield instead of putting it into your graveyard.
So...if a person were to cast an instant or sorcery attempting to remove Loxodon Smiter...it would come back to the battlefield? Does this mean it can only be removed from the battlefield by combat damage? Having a tough time understanding what "can't be countered" in this context means.
