Six Samurai, Dark Armed Dragon Return and Gladiator Beasts are currently the ones to be seen with. DAD Return was the only thing to be hit by the mid-format ban list but it still works fine, probably still the most popular one though. Along with the Six Samurai, DAD Return is basically getting a load of big guys out quickly and beasting down the field. Gladiator Beasts are a bit different in that when they attack or are attacked (presuming they survive) they go back to the deck and get you a new guy out, the main focus of winning with one of these is probably on getting the big fusion guy out.
You should hold off for a bit longer until the next ban list as everyone is really sick of the pure sackage associated with the current meta, a lot of good players have given up because it's that bad.
