ok, so if got this right... first you roll to see if you get + to the real roll? ie, first both players roll for the tarot... on a tie you get -1, otherwise a +1? then you roll to see who goes first, and add/subtract from your result? what if you get another tie here?
also if i'm understanding this correctly, this means that the tarot has a chance of giving you +1 for 83.333~% chance. further this would mean that your chance to win increased to 58.333~% on the "who goes first roll"? Though at th same time, 16.666~% of the time it becomes 41.666~%... meaning the actual increase to you win probability is less than 8.333~% (6.944%.. something like that? i DID fail statistics though so...)... is a 7% increased chance to go first worth 15 points (of course unless my math is wrong, which it likely is...)?
