Wow, I read thru this thread and really only one post (lapping) impressed me with choice of decks, this is sad. I guess I don't know anything, heck I've only been collecting cards for 15-20 years, lol.
Listen folks, play and practise with whatever you want, but always perform with cards people know. Put yourself in their shoes, they are already suspicious of what you're doing, don't make it worse by using Vipers or Black Tigers, or some other space age deck from the latest card retailer. Bikes, Bees, Arrcos, or TH9s are found easily by everyone, and all of them are quality decks. Remember YOU make the cards look good not the other way around.
