So I challenged a top 50 deck and was pleased to beat him easily because he didn't play once. I was even more pleased when I then won 3 Pulverizers. It seemed that he had nothing but Pulverizers(I'm hoping one of you might now how this happened). This was also shortly after I had chosen pulverizer as my final quest reward. So I now have 4. I was thinking I should make some sort of deck using them which is what I want your advice for. What kind of deck should I make. Perhaps something using flying weapons?
I really don't think there's an effective flying Pulvy deck, but you never know. I've honestly never seen one posted here in the forums, though it has been suggested a few times. I think if you really want to make a flying Pulverizer deck, trial and error with the trainer (

Other than that, my advice is to hang on to them until you have 12. You'll never need more than that (6 upgraded, 6 unupgraded). Pulvy's are very useful in Rainbow decks, so you may want to check out the rainbow/anti-FG deck sections, here on the forum.
As for the t50 account you won it from, that's known as a "farm". A farm is a deck set up by t50 players to help other players win rare cards. It essentially consists of a few rares (usually 2-3 different types, 6 of each), and a few pillars. This way, you'll have an extremely high chance of winning one of these rares in the spins after you win the game. (:
