There are 17 monster decks. One of each mono color (5). Each dual color (10). And 2 dragon decks.
The decks are inspired by the decks in the video game.
But they need to be worse because the AI is good in the board game (you're playing against a friend)
Any player that isn't busy will use the monster deck against you.
These decks were designed to use classic cards, and have a funny win con, where everyone knows what the deck is trying to do.
Each deck is exactly 40 cards.
To determine which deck you face, roll a 6 sided die: You will face a deck of the color of the terrain you're traveling to. If you roll 6 it's that mono color. Otherwise it's the 2 color deck with the 2nd color as 1=white 2=blue 3=black 4=red 5=green.
