I'm taking notes on what being said here and nothing is being said as to why the cards I listed don't need to be banned or restricted.( A argument can be made for a few post)
I also challenge comments about be when a player knows nothing of me or my play style and says such things like they are right. No one on Earth likes it when people make up things about someone when they are on a public forum. Those things can be see as rude.
Well at least you do say that a few posts say why not, but I suppose, due to your blindness, the situation must be rectified. This has to be done so that even you can understand how this list is bogus and how the very idea is not fitting for this kind of card game. Well to be honest the idea of side decks and bans in general have been dealt with prior, but as you wished, as shown by the highlighted quote, the list you provided is about to receive a painful probing.
Banned- 0 Per Deck/Side Deck
G-Booster
This card is played in one deck that has not really dominated the game for an extended period of time. Sure an argument can be made that it was the BDIF, but not for overly long or by an overly large gap. This card also comes with a significant drawback, which is namely not being able to play other ace spec cards, such as Dowsing Machine, which is arguably stronger. (As a side note dowsing machine is conveniently not on the list despite being basically the undisputed most played ace spec in the format. Yeah it does not look good for this list off the bat)
M Charizard- Flash Fire 013,069,107,108
No form of Mega Charizard EX has been seen in any serious competitive deck. Have a look at nationals results from around the world. Yveltal variants, Virgen and Plasma among others are the decks that are doing well. Despite this you want to ban Mega Charizard? Come on now.
Charizard EX- Flash Fire 012
The idea of a ban list is to correct the problems in a game, at least I presume, though considering how this list looks, I doubt that. It seems like you want to cater the game to suit you, not actually be the best it can be. That being said, where has Charizard EX ever been game breaking? Answer: No where. Next.
Black Kyurem- Plasma Storm- 095
For once a card you could make an argument for... in the past. This card game has a trend to try and correct itself with the addition of new sets. Of course it does not always succeed, but it attempts to do so. And what do you know, it worked this time. Druddigon makes it so that this card is no longer a problem.
Sableye Dark Explorers
One of the best card ever printed, sure. However once again the game has corrected itself. No serious deck runs more than one sableye. I mean when I won nationals a few weeks back, I played one sableye. Never did I use it in a game that I won. This card is so broken. /sarcasm.
Crushing Hammer
This list is getting repetitive. Hammer spam was a thing for a while and not really overpowered ever, but it is barely viable now. You want to kill it? Kill a tier 2 deck for diversity. Please tell me you understand how messed up that is.
Mewtwo EX
When was Mewtwo EX last a major major threat? Oh let me think, I suppose one year ago. I mean sure it was decent after that, but never really best card in format since then. Ban it to 0 copies per deck? Smrat.
Yveltal EX
The single handed best card in format at the moment. Best card ever printed? Maybe, but probably not. One of the best offensive cards ever printed? Definitely. However once again consider why would you ban this card to 0 copies in a deck. No deck could play 1 Yveltal EX and would be broken because of it. However if there is a single card in the game that deserves a nerf, it is this and hypnotoxic laser. (Side note: This is not bias against these cards because I hate them per se, I won nationals playing both in high quantities of my own free will, if I have free will, but that is not part of this discussion)
Dark Claw
Let's ban Dark Claw entirely, but not ban Muscle Band entirely. Why? Hint: Dark Claw is 100% outclassed and essentially a worthless card now, except for possibly better artwork in an entirely dark deck. That warrants a ban. Suuuuuure.
Let's take a break here and notice that there are so far 0-1 cards that should be limited. Good job.
Limited- 1 Per Deck/Side Deck
Professor Juniper/ Professor Sycamore
Nothing about these cards is inherently overpowered. I have never lost a game because my opponent played a Juniper. Seriously looking back at history, this is not even one of the best supporters ever made. Sure it is good, but Collector, Roseanne, Mentor, Cyrus and Castaway to name a few a pretty much better. And there was no need to ban them. Get the point?
Enhanced Hammer
Hey let's ban a nerfed Lost Remover to one copy per deck. Tell me you see how that is so stupid.
Hypnotoxic Laser
Uuuuuuh a second kind-of almost legitimate card to nerf. Nothing to say here. HTL is strong and I suppose if one wanted, one could test it with some for of restriction. However there is no real need for that as the game has been made with HTL in mind, so other decks not playing HTL now, would get a massive boost if this were banned. That is of course unless you nerf them too. Wait a second... that is exactly what you are doing. Meddling with the format so that it is how
you want it to by making it worse. Lower everything except a select few from a 100 to a 50. Does nothing, but help the select few. You should become a politician. Oh wait never mind, every suggestion you make is unpopular. Go become a republican.
Pokemon Catcher
This card is not broken at all anymore after the nerf of a coin flip. Sure it brings luck, but it is not broken. A card game will have luck. Coin flips are a part of this game. Get out of here.
Lysandre
This is a supporter of a previously great card, making it balanced. In the history of this game the Gust of Wind effect has been used to great success, bar Catcher no flip/Gust of Wind and arguably Reversal/Catcher with flip. Did I just contradict myself? No. Catcher with flip is not a ban worthy offense, as it does not break the game, however it is not a success.
Klinklang (Plasma Steel)
Not played. Next.
Energy Retrieval
Broken. So broken. I can't believe how broken this card is. I mean my opponents forfeit whenever I have two energy in my hand.
Superior Energy Retrieval
Above on steroids, but nowhere near being broken. Cards can abuse this card and the previous card, but even they cannot abuse them in a broken fashion, but even if they could, it would not make this and the above card broken.
Professor Letter
Great card. Broken? No. Reason? Two energies provides consistency, however it does not instant win you the game or give a massive unfair advantage.
Leafeon -Plasma Freeze- 011
No winning deck bar two have even played Leafeon. Only one of these decks really did well. It did not dominate the format. It did not have Leafeon front and center. Leafeon is not broken and no four Leafeon in play is not an automatic win. Come back to reality.
Reality check: At best you have listed 2 cards that could be nerfed, not banned, but I'll grant you that. 2/19. Great list.
Limited- 2 Per Deck/Side Deck
Aromatisse (Fairy Transfer)
Has won no nationals if I recall correctly. If it has, at least not many. Not broken. Not over centralizing. Not ban worthy.
Emboar (Infernal Fandango)
A good card no doubt. Has it dominated the format? Yeah, thought so.
Blastoise (Deluge)
This deck was possibly BDIF for a while. Then it was nerfed with things like Druddigon and it is no longer an issue. Do not kill it further. You cannot create fun and strategy by limiting decent (read: not broken) archetypes.
Keldeo EX
Again is not a problem, unless it's checks are removed. Oh wait, you want to ban Mewtwo and Yveltal? Why on Earth? A game has been designed by its creators in a way that would not be broken (and it currently is not broken) so banning something could upset the situation as it does here. In the real world this card is not an issue.
Garbodor
Garbodor blocks abilities in a way that requires a stage 1 and a tool, which your opponent can remove. How is this broken?
Trevenant
Trainer lock is annoying, but Trevenant has not dominated the game or won anything significant or done anything seriously note worthy. Not broken.
Dark patch
A third candidate for something that could be nerfed as it has created a deck that has been on top of the game for a long time (Side note: On top, not dominated). This, like Yveltal and HTL, is something one could consider a nerf on. Except that it will be rotated in a month and a half. On top of that it has not stood on top of the game alone, except during 2012 Worlds.
Blacksmith
Has yet to prove any level of overpowered characteristics? Therefore the logical conclusion is to ban it. Seems logic.
Colress Machine
Is speed Lugia a problem for the game? Answer: No. Is a deck that abuses this a problem for the game? Answer: No. Is this used in one or maybe two decks? Answer: Yes. Does this make it broken? Answer: No.
Muscle Band
Oh here we are. Dark Claw > Muscle Band my friends. Dark Claw > Muscle Band. Now tell me. Which deck in the format gets an unfair advantage from this card? Oh wait, every deck can play it and no deck can play it in such a way that is greatly better than at least a few other decks. Not broken.
Silver Bangle
You complain about overpowered EX cards. Then you ban a card that balances the situation. What do we call that? You decide.
Max Potion
No deck abuses this card. No deck. None at all.
N
A great supporter no doubt. Much needed in this format as no searching supporters or draw Pokémon exist. It is vital for consistency. It also brings in a form of deck management for the late game, which is skill, which falls under the category of strategy. You want to make this more strategic. Your plan to do so: Step 1: Remove strategy. Step 2: God knows. Step 3: ??? Step 4: Profit. (Side note: This plan is so bad that a mere 3 step plan without ??? or god knows would not have sufficed.)
That was that. How many even debatable cards were there, when I am being generous? 3? Out of? 32. 3/32.
I don't know why, but you seem to want to ban most playable cards even though they are not breaking the game in anyway. Good does not equal a ban worthy offense. Great does not equal a ban worthy offense. Playable does not equal a ban worthy offense. The only thing that equal a ban worthy offense is if something is broken and arguably you have mentioned 3 cards that are exceptionally good, but not broken necessarily.
Returning back to what I said. You are wrong. I just showed why. Now you say you play Zapdos and that this list represents what you think is broken. This qualifies people to make judgements about how you play the game. I will refrain from doing so as this post was quite aggressive, but how could it not be? Otherwise it would have been much too boring to type up. As a final side note, the language in this post is overly crude due to the length and time I typed it, as well as the fact that it was so repetitive due to the nature of the task.
