Yes, because everyone that tops tournaments play 40. Come on Hobaaaaannn gotta give me more than that. I could see if past successors didnt play 42-45, but they have. Not to mention 53 card Merms won a Jump! I mean you cant front on that, if Dao was supposed to lose and go x-2 or x-3 then he would have.
You cant call(well you do w/e you want obv) knock the notion when, I cant stress it enough, there has been success with more than 40.
Thing you need to focus on now is making sure you actually beat these people that play more than 40. Thats good for your right? Take 'advantage.'
Edit: Yes...neg all you want randoms. Like I give a fuck. Thing is, you cant really argue about things like this any longer. We've gone as far as seeing videos and walkthroughs of why 40 is better than 42. Theres also been discussions on why running 42 wont affect your experiences by a large margin. While the literal statement may be true, people are still playing 41-45(and in 1 case, 53) in decks. I mean, iirc a player such as Sorosh Siberian played 42 card Fabled, one big reason that was stated was the fact that It made siding easier. If you can up you deck count without hurting overall consistency to the point of non-playability, and help yourself as a player with siding easier(not everyone is solid with it, including me sometimes), why not up the count.
This is Yu-Gi-Oh; Anything -can- win. It -shouldn't- be made easier at the expense of optimization, because it's easy enough already to make those sorts of decisions if you're actually good at the game, and won't truly get any easier just by making your deck worse. And if anything, not knowing a difference means you should be focused even more on optimization, because if you lose due to that, there won't be any way to reasonably tell why you lost barring the sudden onset of omniscience. You should care more about why you lose than why you won, and having a subobtimal deck prevents that assessment from being as accurate as it should be.
Justifying suboptimal choices (in both plays or deck choices) just because you don't think it'll make a difference, or it makes building a deck "easier" is, in my opinion, the hallmark of a mediocre player, as well as chalking your losses up to luck (and not trying to better yourself or your deck as a result,) which is the only thing having a suboptimal deck truly propagates.
just my 2cents
