Yes. The true reason Lavi doesn't just decide to attack with his 'question-mark' stamps is because he knows better. They just spin around like a roulette until it lands on one of the others he knows how to use already. Needless to say, he was none too pleased with this discovery.
In other news, finding references of his other stamps is way too freaking difficult. Featured stamps are Fire, Wood, Heaven, and Mystery Stamp.
