Don't want to quote and tag everyone, but as long as everyone is paying attention, that shouldn't be an issue.
Stadium wars have been important since the latter half of the BW-era, but yes I suspect they are going to become much more important again. It isn't so much that they were unimportant pre-rotation as much as certain decks just did
not have room but were awesome in other ways, so they could get by making that cut. I am thinking we are also going to see a lot of mixed Stadium lines, because there are a lot of them that just make good TecH (like
Silent Lab) while others are just great for a particular deck... except in the mirror, where getting rid of it can lead you to clever plays. Well, in some hypothetical cases.
Anyway, at times when Stadium cards have been super-duper important, decks have actually run four or five as a common amount, with certain (competitive) decks going as high as eight. Exactly when is a bit hazy, but I'm talking like back in 2004, 2005, or 2006 (I think). So a 2-2 or 2-3 split might become the norm.
Or as we've been discussing, a
Paint Roller or two, or a
Delinquent or two. Then there are the decks that just can't use any Stadium well enough to bother, in which
delinquent can still work as TecH thanks to
VS Seeker, but if you have
no Stadium cards in your deck, you'll probably need two or three
Paint Roller. Personally I believe the two are pretty evenly matched up; I tried both when they were new and too often they were dead draws. Ignoring that it might reshape the entire format, if
Battle Compressor were still legal, I believe
Delinquent would have the ultimate advantage. Using it well is about timing;
N is better for hand disruption largely because its
N and you're often using it for draw power at the same time.
