It's funny, I always have a good look through the used decks at our FLGS. They're generally picked over and don't appear to be much good. However, I found one with a Restringuntus. It doesn't have much in the way of protection for it, but what it does have is 21 creatures and many annoying constant abilities. The problem opponents run into is even their board wipes seldom slow it down much, and it has the ability to cycle so quickly. It's funny that this was a trash deck for someone who probably never even played it.
I do think people tend to underestimate decks that don't fit their ideal deck types—known combos and synergies.
My son's also has a deck that's now 11-1; it won our last FnKF. It has a ton of artifacts and creatures, but very little about it stands out. I was able to defeat it with this trash deck, but I'm still playtesting to see how well it does against a wide range of decks. The thing that stands out to others is the Bad Penny and 3 Seeker Needles. Other then that, the deck list looks very unassuming. So, they're looking to respond to the Bad Penny, but the Martians and Brobnar are huge threats, even if they don't look like much at a glance.
I'm just wondering how many of you have favorite decks that were other people's trash or decks that is much more than the sums of its cards?
