I think the Gamemaster's Apprentice is one of the coolest GMing tools I've ever seen. When I first got it, I thought it was an interesting device, but now that I've had some time with it, I have come to use it for so much more than I had initially thought I would.

I use it not only for random die rolls and names, which is plenty useful, but for sensory, directional, environmental, and story-telling inspiration, both in-game and during the planning phase. The information on the cards are game- and genre-agnostic, which allows the GM to take whatever the Gamemaster's Apprentice gives them and fit it neatly into their story.

The card stock is very nice and great for fidgety card shuffling.

I can't say enough about the Gamemaster's Apprentice. I recommend it highly.

The one bit of feedback I have on the Fantasy Deck specifically: I feel like all the fantasy illustration makes the content on the cards hard to read. The layout and design of the Base Deck is much more clean and organized. The Base Deck illustration is tastefully done and stays out of the way of the content.
