I should also add that I'm a fan of enthusiastic posts discussing new cards. I don't share the sentiment that it's embarrassing to enjoy musing over novel possibilities and that such discussions are inherently ridiculous. The recent troll post I felt was lighthearted enough that I added a jubilant comment. Discussion of why cards are unplayable is just as useful as discussing why they are unplayable. Never stop learning.
It was meant to be lighthearted and I deleted it when it was clear at least one infrequent poster thought it missed the mark. While enthusiasm is good, posts concerned solely with card names or card art are little more than spam. Posts with one sentence comparisons add almost nothing - you should at least take the time to establish why you think a card is comparable. And while there is a role for comparisons, the problem is that inappropriate comparisons derail the conversation into discussing the roles of the card used for comparison. Many of these posts and those in the Teferi thread are actually focused on why Tezzeret The Seeker isn't great right now, which isn't the point of a spoiler thread.
So, @Topical_Island, @Protoaddct , @brianpk80 , thank you for taking the time to write substantive posts. @Protoaddct I think you are missing the mark with most of you comparisons, falling into the same pitfall you've identified for others. The only Walker you've listed whose primary role is drawing cards is really JTMS. The other walkers you've mentioned share superficial characteristics and are improper comparisons.
