I had an idea about a possible improvement over the
currently published movie: what about defeating Heishin early in order to get a strong card or two?
If you don't know this game:
This is a collectionable card videogame from the famous Yu-Gi-Oh series. Its quirk is that you may summon monsters by doing a chain summon, that is selecting more than one monster card which will fused in the chosen order, two at time. You can have the list of possible fusions here:

Another peculiar thing is that when you summon a monster, you have to choose between two astrological signs, which will give that monster a 500-points advantage or disvantage when fighting a monster with a different sign set.
When you win, you get a card as prize, which will depend on the characted defeated and your
luck. Intial deck is also very random.
For the rest, the rules are the same as traditional Yu-Gi-Oh play.
