What falls under the category "draw"? So far I have been interpreting it as I get 2 endurance during the draw phase for drawing 2 cards, and any other time you are instructed to "draw" a card, but what about when a card is put into your hand from the draw pile, but not through a "draw"? Example, The baxter building. If I turn over an equipment or 2, do I get to gain 1 endurance for each card I put in my hand or do I not because they were not drawn? I would think you don't get to, but I am not sure. Thanks in advance.

Tutoring, fetching and filtering are not draws so I'm gonna go with only the successful resolution of effects which instruct you to draw cards will trigger Spoiler's power.

The word "Draw/draw" itself must be used in the effect text inorder to Trigger this effect.

As a note, you might "Draw" right in the middle of an effect and Trigger this, but this effect will add itself to The Chain after the resolution of the draw effect.
