Howling Mine (9ED)

Artifact

At the beginning of each player's draw step, if Howling Mine is untapped, that player draws an additional card.

Legend has it that the mine howls out the last words of those who died inside.

If Howling Mine leaves the battlefield before it resolves, then the last known tap or untap state of the card is used for resolution.

It does not trigger at all if this is tapped at the start of the draw step, and it checks this again on resolution.

The additional draw is separate from any other draw during your draw step. It happens when the triggered ability resolves.
