One of the clauses that I see some debate over is the OHKO clause, namely the clause that blocks moves that kill in one hit, regardless of defense or HP and such. These are disliked by the general higher level members for the very reason that while they have a poor hit rate, they can instantly destroy a wall, something that Pokemon may have not been able to do otherwise, surely. However, there are several reasons as to why these moves aren't merely as bad as they are made out to be. I'll be listing some of the popular arguments and attempt to counter them, as objectively and reasonably as possible.
For your reference the following are OHKO moves: Guillotine, Sheer Cold, Fissure, Horn Drill
The following does not fall under the clause, though it does instantly kill a pokemon if the requirements are met: Perish Song
The first argument is this: They take skill out of the game. To this I'd say that they do not remove skill but they are in fact high risk and high reward moves. They moves are only 8 PP at max with a 30% hit rate, so you are hitting on average 2-3 time if you use it all 8 times. This is a foolhardy assumption, however, as any half decent opponent is not going to just let you use this move (Which, if you whiff it, has no adverse affects to stop the opponent from pummeling you) and instead will begin their offensive.
Secondly, they are easily counterable! There's the most simplest: Use a pokemon with sturdy: A whole plethora of pokemon carry this ability, including some really good ones like Skarmory and Forretress. Guillotine, Horn Drill and Fissure don't hit certain types either, so that's always an option. Also: Substitute makes it so if the OHKO move hits it, it only breaks the sub. Also: Pressure severely reduces the amount of move uses from 8 to 4, just keep that in mind. Focus band and sash also work, but are not that good outside of leads (sahs)
It is also a move that can't be used blindly, sure it can kill, but so can a powerful damage dealing move on the right opponent! Are you sure you just want to give free switch ins to that Salamence around the corner? Nobody does. It's high risk, high reward at its best. Some may argue that this should be taken out as much as possible, but in reality it is a type of playstyle, similar to offensive, stall and the sort. Which also means you'll start seeing more variety.
This will not reduce variety at all, and will in fact open up interesting sets such as Restalk Lapras with Fissure and Sheer Cold, and it will allow some pokemon like Mamoswine who get totally walled by Bronzong or something to have a chance, if nothing else, to get past the wall. EDIT:Mamo doesn't get Sheer Cold it turns out, only fissure. Sorry Mamo, you're still stuck. The only thing it may do is reduce some quantities of No Guard Machamp, but that is not all Machamp can do, of course. (And in fact, that becomes a mindgame in itself, guessing whether to try to OHKO or if it has guts).
So basically, that's all I have on it at the moment. Feel free to point out logical flaws and I'll address you as soon as I can.
