Heh....I haven't seen jinzo's in a machine deck in ages...only time i see him now is in control decks for lockdowns.
You have a good point though..that could happen...but I dont know how how many people want to use that strategy since it can lead to dead draws until you dump them. At the moment I see more pure cyber type decks using the new cyber dragon Zwei to speed things up to get out the cydra fusions easier; along with a etlanin or two for support if you need a last ditch strike.
Who knows though...maybe jinzo will see more play...but it has to be used effectively...frankly the last time i saw 3 jinzo's and 3 returners in the same deck was in a jinzosworn deck (Yes..more ls variants..).
Regardless...machines are looking pretty strong again, so maybe we see more machine decks come out and compete with current meta-game decks.
I personally wouldnt mind trying out a machina or dark machina deck on KC, or maybe even a new age Cydra deck wih zwei, but I doubt we're getting absolute powerforce or that structure deck anytime soon
