Gustaft, Center Ballista/Rulings


 * Gustaft, Center Ballista is only crossed if you have a Dora, Roaring Left Gun on its left and a Doslaf, Roaring Right Gun on its right. Gustaft is not crossed if either Dora or Doslaf is on the field but the other is not.
 * Gustaft, Center Ballista's ability works as follows: The first time Gustaft would be banished in any particular turn, it isn't banished. However, after the first banish fails, it loses that ability for the turn, allowing it to get banished by subsequent banish attempts.
 * If Mušḫuššu, Phantom Dragon Princess or Code Heart AMS attacks while a Gustaft, Center Ballista is in front of it, and Gustaft is chosen to be banished by their effect, Gustaft's ability will trigger and prevent Gustaft from being banished by the ability. Gustaft's ability is subsequently removed, and Gustaft is banished by battle.
 * If Gustaft, Center Ballista's power is 0 or less, the ability will trigger, preventing Gustaft from being banished once and removing the ability. However, since Gustaft's power is still 0 or less, another banish attempt will occur, successfully banishing Gustaft,
 * If you use Get Index or Bonds of the Same Gun on Gustaft, Center Ballista, you will be able to search for a SIGNI even though Gustaft was not banished.
 * Whenever a SIGNI with Lancer attacks Gustaft, Center Ballista, a Life Cloth can be crushed.
 * Lancer interacts differently with effects that replace the banish with something else than effects that prevent banishes entirely (i.e. "can't be banished"). Lancer does not trigger when a SIGNI has a "can't be banished" ability, because the banish attempt was entirely unsuccessful with no effect. Lancer does trigger against banish replacement effects, as the banish attempt was still successful; it simply resulted in something other than putting the SIGNI into the Ener Zone.
