I believe in objective measurements when restricting cards, and I don't believe your "unique combination of factors" provide a compelling and objective reason for restriction.
The main crux of your argument seems to be interactivity, and that Flash limits interactivity because of the potential speed of the combo. To me, it is not any different than a deck like Charbelcher, which seeks to use it's leverage (speed) to attempt to win the match. In your eyes, it seems that speed is an attempt to limit interactivity, while in mine it is using the advantages of the deck's design. Another observer could say that your own creation (Landstill) seeks to limit interactivity by discouraging the opponent from playing spells, or risk losing to an avalanche of card advantage created by the card Standstill. Should we restrict that card too? I don't think so, because there is no prolonged period of tournament dominance of the card, and no objective reason to restrict it, just as there has been no historical data to support the contention that Flash has demonstrated any tournament dominance for an extended period of time.
Look Jason, that's awesome that you disagree and all, but I'm really not interested in engaging in a discussion about why I feel Flash deserved restriction. It would serve no purpose to me seeing as how my objective has been met. To be honest, I'm only interested in discussing criteria for restriction when I think there is a problem for the format, and since I currently don't see any, it's a discussion I'd rather not spend my time on.
I feel your equation of how Flash attacks interactivity to the function of Landstill logically tragic, but I suppose this is because you have a higher tolerance for early game-ending plays than I do. Again, this is entirely irrelevant to your initial objection. Let's try to get back to that:
Rich, if this was the case, and evidence derived from an existing metagame was largely used to support an argument of restriction, then how could you argue for the restriction of Flash and Crucible of Worlds in the past?
I will submit the following answer to you, again, and hopefully it will address your question:
...regardless of whether you agree with Flash's restriction or not, you cannot deny that the restriction was made after a metagame and semblance of an environment formed and allowed the opportunity for the illustration of problems in the format. You may not agree that problems existed, but you cannot disagree that the information provided by the metagame was sufficient enough to make a call for or against Flash. Now, since we have no metagame or information, it does not make any sense to try to predict the future. If changes are to be sought after, they are going to have to be backed by some sort of evidence, none of which presently exists. If you mean to argue that there is current evidence to suggest that the B&R changes are wrong, I'd be open to listening to whatever evidence this may be.
Along this same line of arguments, there is no reason to restrict Brainstorm, as it simply does not follow any of the previous grounds for restriction, which I think is the point of this thread. All of this, and more, will be addressed further in depth by my nexst article at the end of this week. ; )
That's great. I think that if you really want to make an impact, an article and submission to the DCI is the way to go. I think your timing is very premature, since even if Brainstorm does not match current restriction criteria, that does not mean that it was not a good decision, and more importantly, that it does not create new considerations and criteria for restriction. It may end up having a very positive impact on the format as a whole.
My point was that sounding off in threads on TMD about how you hate the changes probably isn't going to achieve much, since it is very unlikely that the DCI will undo any changes in the near future. However, if it is your intent to pursue the issue at such an early stage in the new metagame, all the best to you in that endeavour.
