Goatball is a 60-card, shared deck MTG format for 2 players with gameplay similar to American football or rugby. But with goats.
Players each begin with 3 0/1 Goat tokens and four shuffled, face-down lands (2x Mountain, 1x Island, 1x Molten Tributary) in play. Then, determine starting player and draw 7 cards each. The starting player has a Goblin Construct artifact token in play, which only has the ability “0: Once per turn, you may equip this to a creature you control. Equip only as a sorcery.” At the beginning of the game, and at the first full turn after a change of possession, both players turn one random land face up. The lands indicate which down it is. After that, only the player whose turn it is flips a land face up during their upkeep. On a turnover on downs, all lands are flipped face down and shuffled, then control of the GC token moves to the other player. The player who controls the Goblin Construct token has 4 downs to score. A player scores by dealing at least 1 point of damage to the opponent with a creature equipped with the GC token. A score is worth 3 points, whereas a score against a player who controls zero creatures is worth 6. Attacking creatures that aren’t equipped with the GC token but are still unblocked do not deal damage to the defending player. After a score, the defending player gains control of the GC token, all lands are flipped face down and shuffled, and that player is now the attacking player with 4 downs to score. The defending player cannot attack, but still takes their turn as usual, with all non-attack phases and steps still occurring. On a turnover not resulting from running out of downs, the player that controls the GC token takes one turn, consisting of a main phase, attack step and end step. They do not draw or untap at the beginning of that turn. If, after that turn, they still control the GC token, they have 4 downs as usual to score. If the GC token is ever destroyed, the down is over (all non-attack steps and phases still occur) and a new GC token comes into play unattached to any creature for whichever player is now in control of it. Any destroyed Goat tokens return to play on the first full turn after change of possession. Each player should always begin a possession with 3 0/1 Goat tokens.
At the end of any player’s turn, if a player is ahead by 10 or more points, or if a player is compelled to draw from an empty deck, the game immediately ends. In case of a tie, an overtime period is played, with each player getting 4 downs to score. If still tied, the game is a draw.
All other normal MTG rules apply.
