If you have a set BoM, you can just flip Jinzo face down and use your trap the very next turn.
Or if you have any spells or monster effects that can get rid of Jinzo the next turn, it's also an option. But you have to make sure that you survive this turn.
But if you set a card, it's technically a -1 for the opponent. Otherwise, it's a +0.
It's just a monster that Espa Roba used in the anime. But it was just a normal monster there and wasn't used as a trap card or anything like that. Not sure about the manga though.
This card is excellent and it goes hand and hand with Dark Necrofear. Whereas Dark Necrofear removes cards from the graveyard to summon itself this card is able to be special summoned when monsters are banished.
if you use the combination D/D/D Caesar king of waves and D/D/D arc, queen of oracles you can easily counter this OTK and secure a win against it or increase your life points in your favor.
