To be completely honest, I think the standard z kommo set people use is pretty stupid and just following a trend that some teen started without thinking. the +speed berry belly drum also is pretty dumb. Ive only seen a few people do it correctly and make me hit that GG but none of them were the actual set(s) that is(are) recommend. If you're going physical, Z + dragon dance is the wave and make sure your moves are set up b/c the moveslots are heavily team dependent and you do not need stabs on it. I personally recommend special or like specs or scarf but that's just my personal preference. I know people think I have an attitude but that's more reactive than it is my innate nature. I just want people to think for themselves and learn how to actually teambuild. So ya that's what I think any thoughts?
If I played it a little smarter instead of trying to sweep turn 4 or get a better roll on scizor I probably win with just kommo. I've found on the mid-ladder at least this is pretty consistent of teams that don't pack tox or mage (which are the bane of this sets existence). I will say I think drain + poison jab is best move coverage.
Update: Here's a slightly higher quality replay where Kommo-o cracks what loooks like a pretty standard OU team wide open for lele and/or lop to mop up.
Since I have a couple replays I'm going to make my case for Kommo-o. Double dance clang soul is a very threatening set that has 3 hard counters that I've encountered playing up from 1000 to 1600. Mage, Tox, Unaware Clef. Unaware Clef doesn't like switching into poison jab as it's taking 40% and a chance to get poisoned. Frail fairies + bulu are dying to +1 poison jab, and bulkier fairies are falling if weakened. Ddance is critical to further boost your speed and attack and Kommo frequently gets 2 boosts and sometimes more as people try and fail to intimidate/revenge kill etc. This set alone should get Kommo ranked in C- as it destroys teams without its counters or if said counters have been eliminated. The only reason it shouldn't be higher is its counters are excellent mons that are pretty damn common.
Now, Kommo has options beyond just Double dance clang soul even though I think this its best and should be standard set. Sub/BD is a high risk high reward gimmick that punishes mage and tox, and has surprisingly many setup opportunities. In theory a straight offensive physical dragon dance set with close combat isn't bad as how many fighting types can actually boost their offenses, but I haven't tried it yet. Most importantly when it comes to ranking a mon. Kommo-O is a unique threat. There isn't anything else in the metagame that quite matches it. As a z-booster it has advantages over victini, jirachi, and lol porygon z in that it can further boost and heal itself. As a sub-bd it is scarier than chestnaught and forces switches to mons it sets up on more readily. In my opinion the Komodo Dragon should be ranked in C.
I'm curious Thunder Pwoell what you mean by a special set. I've done a pretty in depth analysis of kommo trying to use it, but at least on paper all its special sets seem to be just for surprise value and really inferior to its physical sets.
