Spy Cards is a type of minigame in Bug Fables. It is first available after Team Snakemouth talks to Carmina in Underground Tavern, and is later available in other places, including the matches with the Four Card Masters and the Spy Cards Tournament on Metal Island.
Team Snakemouth first needs to select 15 cards from the Bestiary that they currently have Spy data on, so a filled Bestiary contains all 90 kind of cards. First, choose 1 Boss Card. Then, choose 2 Mini-Boss cards that aren't repeats. After that, choose 12 regular enemy cards consisting of Attacker and Effect cards that can have repeats. Team Snakemouth can save this deck for later matches.
Both sides starts the game with 5/5 HP, 2 TP and 3 cards in their hand, and they get 1 more TP and 2 more cards every round. (If you have 0 cards in your hand, you'll draw 3!) The TP will be capped at 10 at Round 10 or later. There is a hand size limit of 5 - you won't draw any more cards if it would put you over this amount. After choosing the cards to play, the game will calculate both side's ATK and DEF based on the following value:
- The ATK of all player's cards is totaled together.
- The DEF will reduce the other side's ATK, unless it's piercing.
- The Coin (X) effect will flip the said number of coins, and triggers the effect when the coin gets a head (indicated by a smile).
- The Lifesteal effect heals the respective amount of HP when the user wins a round.
- The Heal effect heals the respective amount of HP regardless of whether the user wins the round or not.
- Unity gives additional ATK for other cards of the same tribe.
- Empower (X) Increases the ATK total for each card of X tribe.
- The VS X(Y) means that if the opponent includes the X type of cards, the Y effect will be triggered.
- Tribe (X) means when there are X numbers of a tribe, an effect will trigger. Empower gives each individual a certain type of cards more ATK.
- If ATK (X) means the effect will trigger if the attack power is over X.
- Setup gives Team Snakemouth an effect next turn.
- If X means the effect can only be triggered when the said card is used together,
- Numbing effect can disable an Attacker of the enemy's side, reducing their total ATK.
Team Snakemouth with a higher ATK total wins the round and deals 1 point of damage to their opponent. If the ATK totals are the same, then neither player loses HP. The game continues until one of Team Snakemouths wins by reducing their opponent's HP to 0.
