Summonball is a variation for 2 teams of 3 players.
To score goals by bringing the ball to the edge of the game board.
A token to represent the ball. For example a small coin.
Location of the Ball
If the ball isn't in play a Summon in the No-Attack Zone may be deactivated (like activating a crystal: rotate the card) to receive the ball. The ball is placed with the Summon card and is said to be held by the Summon.
If the ball is in play it has a location. The ball is either directly on the board or held by a Summon in play. In the latter case the location of the ball is the location of the Summon holding it.
If at any time the ball is located on an Inner Summon Dot the ball leaves play.
If the ball is on the board and a Summon moves to its location the ball becomes held by the Summon.
If a Summon holding the ball leaves play the ball is placed on the board on the location of the Summon that held it.
A Summon holding the ball cannot warp.
A Summon that holds the ball may shoot the ball to a location on the board instead of attacking provided it could attack an opponent's Summon at that location. (If the Summon can't attack because it has already attacked this turn it cannot shoot the ball either.)
If a Summon is on the dot where the ball is shot to the ball becomes held by that Summon.
If no Summon is on the dot where the ball is shot to the ball is placed on the board at that dot.
If at any time the ball is located on an Outer Summon Dot the ball leaves play and whoever controlled the Summon that last held the ball before it moved to the Outer Summon Dot scores a goal.
The team that scores 2 goals first wins.
If a Summon holding the ball is in the No-Attack Zone at the end of its controller's turn the Summon receives 3 damage. (This penalizes hogging the ball where Summons can't be attacked.)
If a Life Base holds the ball at the end of its controller's turn the Life Base receives 3 damage. (This penalizes hogging the ball with a hard to destroy Summon.)
Exclusion of Victory Conditions
If a Life Base moves or warps to an Outer Summon Dot it's owner does not win the game. The Life Base is discarded however at the end of the turn unless it moves off the Outer Summon Dot.
If a Life Base leaves play it is immediately placed on the Inner Summon Dot of it's owner under the control of it's owner. If a Summon is already on that dot that Summon is discarded. Life Bases leaving play do not cause their owners to lose the game.
If the last card of a deck has been drawn the discard pile of the player owning the deck is shuffled and placed face down as the new deck for that player.
