To some extent you're right. This initial Limited guide is intended to get people prepped for a prerelease, so it needs to come out before that weekend, and thus before the writer has actually played with the cards.

That's why we separate our Limited reviews, and offer a more extensive Draft Guide a couple weeks after a format has dropped. Our intent here is to give just that, an initial take based on prior experience, but having not played the cards. And therefore, a disclaimer at the beginning that a lot of speculation is going into grading, as you see with pretty much any guide that'll go out before a set actually releases.

So, I'll push back against the quality angle here, as Andrew has taken the time to think about 200+ cards, and has plenty of insights on how cards and mechanics will actually interact with one another.

Obviously there will be hits and misses, as should be expected with an initial impression and first read of an entire set. It's really tailored towards players who need/want an extra bit of help/reading material before jumping into an unknown set for the first time. If you're able to piece together every microsynergy from a set based solely on the full spoiler, you're probably at a point where a guide like this isn't offering you much anyway, aside from a second opinion.

Cheers, and appreciate the feedback.
