Removed the copy/pasted definitions from my OP, and just quoted Tang on what the purpose of this thread is. I guess it was pretty arrogant of me to think that you guys needed my help in coming up with definitions. Now that I've read through all the arguments and proposals, I'd like to recap on what's been said so far.

I am also not too against the idea of nerfing a move's power with clauses, while I would agree with someone like Obi that Clauses have to be enforcible in game (like sleep clause).
I am surprised that this got such little discussion, as it is a system that we already implement to great success in order to keep pokemon like Breloom and Gengar from being broken. Basically, if an attack is deemed too powerful, place a limit on how that attack can be used. At the moment, players are not allowed to place more than one opponent to sleep, since otherwise players could completely shut down an opponents entire team, especially with substitute support. In a similar vein, we could clause other attacks such as making OHKOs fail if used in succession, or as Chou suggested making SR deployable only once per pokemon, which would theoretically bring a lot more balance to the current SR/RS/Ghost attack triangle.

A move can be considered broken if it satisfies both of the following conditions under common battle conditions:
I: The usefulness, efficacy, and / or viability of the move is reasonably independent of the user.
II: For a player to counteract the effects of an opponent using a particular move (or class of moves) it is necessary to design his or her team such that it is not competitively viable if an opponent does not use the particular move (or class of moves) in question. -Caelum
A sound definition at first glance. It could be argued though that "competitively viable" is defined by what is allowed in competitive play, not the other way around. Another thing about this definition is that it opens the door to reasonably debate the status of Outrage/DMeteor. If my opponent is using multiple Dragon pokemon with Outrage/DMeteor and an extremely high offensive stat, than I need to have a team with multiple steel types on it, but then my team becomes weak against a team that uses Fire attacks. I can actually see this phenomenon occurring while I play on the ladder when my Scarftran takes out 3 or 4 pokemon in a row after I've removed/weakened their Heatran and their 1-2 fire resists.

A conscious effort to increase the reliance of luck with little or no drawback and / or significantly decreasing the skill in a battle.
The classic argument for why OHKO/DT are banned. Hip and Tang critique this better than I can.
* How do you increase luck with no drawback? Surely increasing luck is a drawback by itself. -Hipmonlee
* Skill is an act of manipulating random variables to your favor. Saying that Double Team is "skill less" is a bit silly and extreme. -Tangerine

A move is broken if it makes an otherwise balanced pokemon uber.
Not quite what we want imo, since if a move only makes one pokemon uber by being legal, than it's the fault of the one pokemon, not the move.
* Banning a move obviously wont help if only 1 pokemon benefits from it -KD24
But we're getting close.

If that one move makes multiple Pokemon broken, however, it could be safe to say that it is the fault of the move.-darkie
Posted by Tangerine:
A move is "broken" if it allows a significant number of Pokemon to break the clauses of uber under standard conditions. The significant number of Pokemon is to be debated - should we ban one move to make two Pokemon "not broken"?
This one is my favorite and seems to be the most logical to me. If two different pokemon are uber, but no longer meet the uber criteria if they both have the same attack removed from their movepools, than it is most likely the attack that is causing those pokemon to meet the uber criteria, and not the pokemon themselves. Although a good point is brought up about this one.
Posted by Blame Game:
If one move "makes" several pokemon broken, it's still ambiguous as to whether the move or the Pokemon are at fault, as long as there are any other Pokemon with that same move that aren't broken.
Posted by Caelum:
If only one or two Pokemon can abuse the moves well, then that is the fault of the Pokemon not the move.
Two things I want to bring up:
1. Beware of lumping attacks together. Even though we say "OHKO" moves, Horn Drill, Fissure, Guillotine and Sheer Cold are unique attacks considering that they are ineffective against different pokemon and are learned by different pokemon, and that goes for all other attacks that have identical effects eg: Double Team/Minimize, Tail Glow/Nasty Plot.
2. We need to know (or I want to know) if it is currently the goal of this thread to come up with a framework that logically justifies and preserves the status quo (DT/OHKO broken, SR/Outrage not broken), or if we want to come up with a valid definition regardless of how it affects our current ban list and clauses.
