Bone Miser’s abilities are triggered abilities, not activated abilities. They don’t allow you to discard a card whenever you want; rather, you need some other way of discarding a card.

If you discard a card as a cost to cast a spell or activate an ability, Bone Miser’s triggered ability resolves before that spell or ability but after you’ve chosen targets for it. If you discard a card while a spell or ability is resolving, the triggered ability resolves after you’ve finished resolving that spell or ability.
