Rules are pretty basic. Each player has a creature Deck. They have to shuffle it and pull the first 4 cards.
Each creature card has Attack, Defense, Health and some effect (Usually a simple effect like "recover 1 Health Point every time it attacks), the maximum base Value of any of those is 9. When a creature attacks another their attack is compared against the defense and the resulting value is substracted from Health.
They also each has a Magic and Weapons deck, they start with 4 cards and draw 1 from it each turn.
Magic cards (the blue ones) have a special effect and a number of uses. Magic depends on tokens (which will just be coins) to use, they usually get tokens from each turn or when they destroy an opponents monster so you can't just spam them every turn. Weapons have no requirements but they have Health that is drained either by use (-1 point every use) or by receiving an attack (at which point they add 2 to the defense pool), they all have straight forward effects, like increasing attack or attacking twice, etc.
There is also a communal Deck that all players have to draw from each turn. It's based on regular poker cards. Each suit has an effect and it's potency is represented in numbers. Hearts affect Health, Diamonds affect Defense, Spades affect Attack, Clover affects Tokens. The red ones increase the affected value by the number (The queen gives +10, the King gives +10 but to 2 creatures, Jack gives +5 to 2 creatures and the ACE substracts 5 from the opponent), the black ones meanwhile are the reverse. I still don't know what to do with the Jokers, but I am open to suggestions. I am thinking it letting you draw 2 cards but I am not sure. Each time you pull one of these communal cards you have to play it immediately.
Whoever runs out of creatures just loses. Can be played by up to 4 people.
The Black and White Spines are for the communal deck, while the Color spines are for the personal deck (Creatures, weapons and Magic).
