Nobody has yet to address the key flaws that it is A. Worse then a +1 boost at best and B. Only lasts 4 turns period no matter what. The problem with Belly Drum is that it would make for a horribly binary mon - either it can drum and do massive damage/ruin the enemy team, or it can't and it just flat out dies without doing anything since any mon balanced around +6 attack dealing massive damage will have to have a piss attack stat to compensate. For the record I used to play NU and Linoone was the least interesting shit ever. He either completely swept you or demolished a lot of your team in totally BS fashion, or he didn't and did absolutely nothing that match.
