One question about this jutsu...how is it mid-range if you have to "Place a paper bomb on your opponent's head".
This jutsu seems more offense-oriented. Again, the opponent is immobilized so you can use that against them. I would use this with swamp of the underworld so that it is harder to realize that it's a genjutsu. However, it is still quite obvious that it's a genjutsu because of the whole butterflies thing (they would fly away from battling ninja throwing jutsu around at eachother).
It's best to use in short range that way you don't have run all the way from mid range to place the explosive. But, it can be done. I can't tell you how many times i've seen this technique win a battle. Nice reasoning for discovering it's a gen, Bush.Yeah i agree with bush, using swamp of the underworld would make it more realistic. The key to a good genjustu is making it so its hard to tell its a genjustu. In this case swamp would do just that. That with a little false darkness could be a good 1-2 punch. Though this genjustu is still quite obvious it is such. I'd use this while im mid range and want to do something to see how my opponent would react. This isn't a justu that'll win the match.
