The Dredge and Shop Strategies across multiple formats

[BruiZar]

Vintage is defined in large part by Dredge and Workshop decks. 2 Decks that require a large amount of sideboard cards to combat. This leaves vintage players with less options for other match-ups. There is a delicate line between executing your own game plan and disturbing it by sideboarding too much against Dredge and Shop. I believe that this is the reason why the performance of Dredge and Workshop fluctuates so much. They are omnipresent metagame predators. They force streamlined decks to deviate from their game plans preventing them from becoming 100% focused. Storm decks are the best example of this. These lists are so streamlined and broken that they can go off on turn 1, but they often lack the outs once a gaddock teeg, ethersworn canonist, chalice of the void or some spheres lock the game up. (Often not more than 1 Chain of Vapor and 1 Hurkyll's Recall).

A deck inherently becomes more powerful, yet also more fragile to hate the better it is developed. Because of the power level in Vintage, I believe its a position to  look how other formats behave.

When Mirrodin was still legal in extended, there was Dredge and Affinity in the meta. As we know from Vintage, Dredge and affinity decks are fragile sleeper decks that require a large amount of sideboard dedication. When 2 decks that require a lot of sideboard dedication are present in the meta, the meta becomes disturbed and the top tier decks may change position.

Meta + Affinity = Balanced Meta
Meta + Dredge = Balanced Meta
Meta + Dredge + Affinity = Disturbed Meta

Legacy has its share of graveyard abuse. There is Dredge, Vengevine/Madness and Reanimator. The lack of a good artifact deck keeps CounterTop at the top its Tier. CounterTop is comparable to our Mana Drain lists with Time Vault Voltaic Key.

In Legacy, there are 2 Artifact decks. White Stax and Affinity. Affinity is not a competitive deck due to its lack of disruption. It's a lot like Goblins, where the objective is to race. White Stax is a little more interesting. It uses Trinisphere, Smokestack and Armageddon to win the permanent war. The problem is that, like pre-golem Stax in vintage, it lacks a clock. Legacy does not have an artifact deck that combines a clock with disruption like we have in Vintage. I believe that once a good artifact deck can be made in Legacy, the meta will shift tremendously, due to the fact that decks have to dedicate a critical mass of sideboard slots to 2 strategies (Graveyard and artfacts).

What lessons from Vintage could we apply to other formats? Are the format-parallels I draw correct? Am I overestimating the impact of these 2 strategies? Discuss.
