Superfight: The Hero Machine Deck Rulebook

The Hero Machine Deck is an expansion for Superfight: 100 cards split into three numbered Hero Machine decks (1, 2 and 3) whose words combine into a character, plus "To the Hero Machine" cards. Its only rules are printed on the deck's black Expansion Explanation Card, transcribed below.

Expansion Explanation Card

Separate the Hero Machine cards based on number.

Add the "To the Hero Machine" cards to the main game's character deck.

When a "To the Hero Machine" card is played, draw a 1, 2, and 3 card from the Hero Machine. Put them in order. That is your character.
