With this new structure in place, a simple rule for fouls becomes apparent. A skater may risk a foul by replacing their played card with the next random card from the deck. If the new card is more successful than the replaced card, it takes effect (altering the hit location or causing extra damage) but the skater’s foul risks being seen by a referee. If the new card is less successful, it must be used anyway.
Some skaters known for playing dirty might gain access to skills/traits that make fouls less visible to referees or more effective.
I'll throw together some play examples with the next post.
