I backed the Indiegogo campaign and I’m glad I did. The Indiegogo had the option for all three decks and right now I can only find what I believe is Volume 1 on the Frog God site. But as you can see, there were three decks. A generic one. One geared for dungeons. And one for wilderness.
So what exactly are these decks? Well, each card has a little bonus or perk for a character. Bonuses, do-overs, confusing an opponent and so on. If you’re familiar with the Savage Worlds Adventure Deck or the Pathfinder Plot Twist Deck then the Dirty Tricks deck is basically the same thing. And yes I have both of those.
The Savage Worlds Deck is perfect for Savage Worlds. And the Pathfinder Deck is great for Pathfinder and 3.x. So if you playing Fifth Edition, or any retroclone then well those decks don’t exactly work. Savage Worlds is a completely different game system (duh). And well Pathfinder is Pathfinder. There’s enough similarity between most retroclones and 5E that the decks will work. So they are pretty edition neutral. Oh and there’s some pretty funny quotes on them too.

Now let’s look at a couple of cards:
Jump Back Kiss Myself: Re-roll a failed Saving Throw
It’s Only A Flesh Wound: Take only half damage
I Know Something You Don’t Know..I Am Left Handed: +2 To-Hit and Damage for 3 Rounds
You’re Going To Shoot Your Eye Out: Missile attack blinds opponent for 2 Rounds.

You get the idea. And what are the rules for using these cards? There are none. It’s up to the GM to decide how they are used at the table. Maybe every player gets a card. Or they only get a card if they do something cool. Or roll a Nat 20. Do NPC get cards? That’s up to the GM too. And that’s when they become real Decks of Dirty Tricks. Personally, I’m still bouncing around ideas how exactly I want to use them. Maybe like I mentioned before. A card for every player at the beginning of a session and then an extra card if they do something cool. And I’ll probably think pull a few for NPC use. Insert evil snicker.
These cards add other layer of randomness that can happen during an adventure. While it put strain on the GM’s well thought plot, it will drive stories into completely different directions. And I think it’s good think. I kind of like when the game reaches out to both the players and GM and throws some crazy out there. You know sort of some of the craziness of Dungeon Crawl Classics.
Heck match these up with the Hireling, Encounter, and Treasure Cards, you can have a crazy session with little prep (but a whole lot of improvisation).
