Incomplete, nonparallel information.

Incomplete information is information that is unknown to one or more players. Nonparallel information is information that is unknown to one player, but known to the other.

Incomplete information usually constitutes the normal draw, cards in life cloth, Life Bursts, or any card in a location that one or more players do not know without use of effects or other means.

Consider: If you have to attack directly with a SIGNI, and attack (and banish) an opponent's SIGNI in any order, what is the optimal way?

Outcome A: Attack directly, then attack an opponent's SIGNI. Attacking directly causes an unknown event to occur (a chance for a Life Burst, from crushed Life Cloth.), making the probability of a defensive Life Burst always present. This will lead to certain states where you will be unable to banish the SIGNI with your SIGNI in the other hypothetical battle, as the Life Burst has already dealt with your other SIGNI.

Outcome B: Attack the SIGNI, then attack directly. Attacking the SIGNI does not cause an unknown event to occur. This means there is no risk of incomplete information affecting game results. The SIGNI will always be banished. The Life Cloth will always be crushed. There is no state where there is a risk of the game state being affected by this order.

This will not always be accurate. When playing, it's also important to consider the converse of the situation.

Consider: Given a 5 card hand, with 1 card that is necessary to keep in hand, you must discard 2 cards: 1 randomly, 1 by your choice. What order is most optimal?

Outcome A: Discard by choice, then discard randomly. An unimportant card is discarded, and there is a 1 in 4 chance that the important card will be discarded randomly.

Outcome B: Discard randomly, then discard by choice. There is a 1 in 5 chance that the important card will be discarded randomly. If the important card is not discarded, then the important card will not be discarded by choice. Therefore, this is more optimal.

Conclusion: Determine what information is incomplete, and what information is nonparallel. Prevent the opponent from gaining nonparallel information. Limit the influence of incomplete information in outcomes. Consider multiple outcomes when unsure.
