I'm suprised how many players complain about shop's power.
As Jsakpc said, the deck follows the B&R list, and good builders found an extra-agressive list, and that works great.
People seem not to admit that a NON-blue deck wins. Where is the problem, i mean, really ?
Is ravager shop unbeatable ? Absolutly not. Is it really good ? Of course; but did it won all tournaments for years ?
Don't you think that an Oath deck can't beat shop ? I've watch the semi between Rich Shay and Pat Fehling, on Inferno Oath. On g1 Fehling kept his 7 hand with : Library,underground sea, Fow and probe. No oath; of course you can hope there is no wasteland or stripe mine, hope your opponent kept a non-agressive hand, hope you draw ancestrall on your lib activation, find G source+oath ...but that hardly happens.
I would really like to know if Brian Kelly would have kept this hand against ravager shop. IMO this hand was great ... against a blue deck.
On g2, Fehling controls ravager with needle, kills threats with grudge and harcasts Griselbrand, everything seemed good...but there was metamorph in Shay's hand. How good it must be to metamorph Griselbrand ! So it was really close but metamorph wins only because Shay was able to cast Chalice on 2. IMO both played well that game but Shay had magic gods by his side.
And this will be my conclusion : of couse Top8 players are really good, but other players are very good too, you need to be lucky to reach top8 and win a tournament, just look at Kelly's 1/4 : 2 dig and almost nothing to play(and compare with 14 draws on grisel activation and finding the answer to avoid a lethale attack of Fehling's grisel by flashbacking his grudge on metamorph).
