Control warrior was moderately overrepresented in this tournament, so you'll see more big value legendaries.
Despite that, there were only 2 shredders in the entire tournament. Neither of the players using them made it to the top 4 (ie their decks were worse.) Tides was singlehandedly responsible for half of the random high value stuff in his greedy decks.
Sneed's just has no identity. It obviously has no place in rush or against rush, and it's viable in perhaps only paladin for control vs control. Even then it's sketchy as hell.
While I think that Trump does have some amazingly educational streams, his focus on value makes players blindly praise the wrong card. Cairne, Ysera, Sneeds, etc. are
bad cards. They find their way into some
very niche decks that attempt to work around their downsides, but rarely has such a deck made it big anywhere. These "value" cards almost never make it to the top of the tournaments. In this case, out of the sixteen decks in the top 4, only Cairne was in any of them, and only in a deck that went 0-2.
Amazingly mediocre cards that appeared more often than Sneed's or Ysera, to give you an idea of how bad they are:
Sprint
Baron Geddon
Deadly Shot
Oasis Snapjaw
Senjin Shieldmasta
Troggzor
Annoy-o-tron
Blingtron
