The art is great and the trap diversity is great. The format works well and allows for you to use them in many different scenarios.. it is a new addition to my DM kit.

Great traps, can't wait to use them on my players... crying is a free action...

Perfect!

Pretty fun and helps take pressure away from setting up everything in advance

01 Technical review
Deck arrived with a mini 12 page user's guide. Its very thorough!

The cards suffer from ther own lack of advertising. It is great quality card stock [Think Bicycle Deck just ever so slightly thinner]. The print is full of vibrant colours. They are plastic coated, so will be splashproof. They actually look waterproof not splashproof. None of this seems obvious from the store entry.

The card layout is incredibly compact without looking tiny or squashed. Follow link provided to see an example of the card.

Notable features from the cards:

Nice clear fonts, great flavour text, the damage on the cards I read were consistent with the DMG 2014 & 2024 [nice] and XGtE, the concept is really clear and the mechanics clearly explained. There is so much to like about these cards.

My one niggle is with the DC's I checked. Some seemed low for a level 9 - 12 trap. That said you can bring the save in line with your game. A good basic rule is set the DC level with the level of the trap. 10 - 12, lower end for damage and higher end for conditions.

02 In game review
The cards are nice and varied. Mostly boilerplate traps but imaginately titled and great flavour text.
They removed all the work out of creating a trap for the table. As mentioned they line nicely with both DMG's and XGtE [or the ones I read anyway].
To badly misquote Lord of the Rings "Looks like traps are back on the menu boys!"

So overall, very excellent.
