Yes, that does seem to make sense. And I agree that it does have some major drawbacks, 4x ground etc. Although it does have some sweet assist moves,(tspikes, dual screens...) and it really does not have to bad stats.
I can definately see where having a group project makes overpowered pokemon, no one wants the new pokemon to have any faults, they want an unbeatable pokemon, the next best thing to a wonderguard spiritomb. Maybe you should make a pokemon with a lower BST and average stats, and then try to make that pokemon hit OU. Kind of like ol'drizzle toad. Great job deck knight and all others. :) 9/10
