Heya, recently me and a group of friends have started playing a custom
card game but long distances prevent us from visiting often. Now I found
out about Vassal recently and wondered if our rules could be programmed
into a module before I start figuring out how it works. (I'm horrible
with this sort of stuff)

Either way:

Preparation

One player takes as his "deck" the 26 red cards, the other the 26 back
cards. Each player's deck is shuffled and stacked face down to the
player's right. Each player begins with 40 life points. A player whose
life points fall to zero or below zero has lost the game.
If four players are around, two decks are used while every player takes
one suit.

In this game, the cards 2 to 9 are knight cards, used for attack and
defence, and the cards from 10 to ace are effect cards.

At the start of the game each player draws 5 cards from his deck. The
players now play alternately. In each turn, one knight card and any
number of effect cards can be played, but at any time there can only be
a maximum of five knights and five effect cards in each player's layout.

[Cards that are destroyed during the game are placed in a discard pile
and cannot be reused.]

Phases of a turn

A turn consists of 4 phases:

1. Draw a card

One card is drawn from the player's deck

2. Main phase

The following actions can be taken:

Play a knight card face up in attack position (AP, vertical) or face
down in defence position (DP, horizontal). In any turn only one knight
card can be played.
Change the position of a card from DP to AP or vice versa. When taking
this action face down cards are turned face up, but face up cards are
not turned face down (this can only be done by means of an effect).
Changing a card from face down DP to face up AP is known as 'flipping
up' and can trigger effects. The position of a knight cannot be changed
during the turn in which it was played from hand, except by an effect.
Activate effects. (The opponent of the player whose turn it is can also
activate effect cards but not knight effects.)
3. Battle phase

Attack with knights (both players can activate effect cards). This phase
does not take place during the very first move of the game. Therefore
the first player cannot attack immediately.

4. Second main phase

Play a knight card (if not already played in phase 2), activate effects.

Carrying out the attack phase

Each knight in AP can attack once. The attack strength (A) of a knight
is the face value of the card, the defence strength (D) is 10 minus the
face value. For example a 3 has A=3 and D=7. A knight in AP always has
strength A, while a knight in DP has strength D.

If a knight attacks an enemy knight in AP, the knight with the lower A
(taking account of effects!) is destroyed and the loser subtracts the
strength difference from his life points. If the knights have the same A
both are destroyed but no life points are lost.

If a knight in DP is attacked, it is only destroyed if the attacker's A
is greater than the defender's D. However the defender does not lose any
life points. The attacking knight cannot be destroyed, but the attacker
loses the difference in life points if the defender's D is greater than
the attacker's A. If a face down knight in DP is attacked it is flipped
up into face up DP, and flip effects are thereby activated.

If the opponent has no knights in play, the attacker can attack his
opponent directly, and the opponent loses life points equal to the A of
the attacking knight.

In this phase both players can activate effect cards.

Effect cards

Effect cards are played in an area below the player's knight cards. Any
number of effect cards an be 'placed' face down during a move [provided
that the player never has more than five effect cards in total on the
table]. Effect cards cannot be activated during the turn when they were
placed, but they can be activated in the opponent's turn that follows,
or any time after that.

10 = Mirror: A knight attack is cancelled and the attacker loses life
points equal to the A of the knight. The player cannot attack with that
again in the same turn, but may attck with a different knight.
J = Bash: Can only be activated when a knight (one's own or an
opponent's) is played or flipped up into AP. All knights on the table
are destroyed.
D = Damage: All effect cards on the table are destroyed.
K = Counter: The opponent's most recent action (no matter what it was)
is cancelled and the card used for it is destroyed.
A = Adjust: the position of any knight on the table [one's own or an
opponent's] can be changed (to AP or face up or face down DP).
Additionally a knight card can be placed in the effect zone as an effect
card instead of being used as a knight. When activated it has the effect
"Equip": the A and the D of the face up knight so equipped are increased
by the A of the equipment card. It is possible to apply more than one
equipment card to the same knight. If the knight is destroyed, removed
from the table or flipped down any associated equipment cards are
destroyed. Like effect cards, equipment cards cannot be activated until
the (opponent's) turn after they were placed in the effect zone, but
after that can be activated at any time, even in reaction to an attack
by an opposing knight.

Effect cards are placed on the discard pile immediately after
activation, with the exception of equipment cards, which remain in the
effects zone until destroyed.

Knight effects

In addition to their normal functions, 4-, 5- and 6-knights can produce
effects as follows.

4: the owner of a face-up 4-knight can exchange it for any of the
opponent's knights. Any equipment is transferred along with the knight.
After operating this effect, the player will probably want to destroy
the 4-knight that now belongs to the opponent, otherwise the opponent
will be able use the same 4-knight to reverse the exchange at his next
turn.
5: when face up, this knight is immune from the effect Bash. If used as
an equipment card, a 5 protects the knight it is applied to from the
Bash effect. A face-down 5 in DP is destroyed by bash in the usual way.
A face-down 5 in the effect zone is not destroyed by Bash, because in
this position it is not a knight.
6: when this knight is flipped from face-down to face up (flipped to AP
in the player's turn or flipped by an adjust effect or flipped because
it is attacked), the owner chooses any one of the opponent's cards on
the table and sends it back to the opponent's hand.
When several effects are activated during the same attack, they are
resolved in reverse order.

Example

Player A has a 4 in hand and a Queen face down in his effects zone.
Player B has a 9-knight in AP and an 8 face down in his effects zone. It
is player A's turn. Player A plays the 4 as a knight in AP and activates
its knight effect to exchange it for player B's 9. Player A then uses
the newly acquired 9-knight to attack the 4-knight. Player B reacts by
equipping the 4 with the 8, but player A activates the Queen to destroy
all effect cards. The Queen destroys the 8, and the 9 kills the 4.
Suppose that in addition to the above, player B has a King face down in
his effect zone. After player A activates the Queen, player B activates
the King. Now the King cancels the effect of the Queen (so that effect
cards are not destroyed), and the equipped 4 has a strength of 12. The
attack with the 9-knight fails and the 9-knight is killed.
Suppose that in addition to all of the above player B has a face down
Ace in his effects zone. After B activates the King, A activates the Ace
and uses it to turn the 4-knight face down into DP. As the last played
card, the Ace takes effect first and the 8-equipment is destroyed since
face down knights cannot be equipped. Next B's King cancels the effect
of A's Queen, but B's 8 has already been destroyed so the 9-knight
succeeds in killing the 4-knight.
End of the game

The game ends when a player loses all his life points or when both
players' decks are empty. In the second case the game is a draw,
irrespective of how many life points each player has.

Possible Variations

This game offers many creative possibilities. One can invent other card
effects, which could even be different for each player.

The inventor often plays with the following additional effects for
knights 2 and 3:

2: If this card causes damage to the opponent, the opponent cannot draw
a card at the start of his next turn.

3: If this card causes damage to the opponent, a card is drawn at random
from the opponent's shuffled hand and discarded to the discard pile.

Cheers
