A pretty clean D/D/D decklist, I'd say. I've been tweaking it for a while, but here's what I play right now. The combos are all intuitive and complicated, so it takes lots of practice to be able to consistently play the deck well. One of the best lines is overlaying Copernicus and Gryphon into Caesar, and then linking off Caesar and another monster (usually Lamia) for Cross-Sheep. This will give you lots of material in grave because the pendulums won't get sent to the extra deck, and it will search Swamp King to trigger the Cross-Sheep with. With this deck, it's pretty important to manage your tuners. Most of your best end board cards are synchros, so you don't want to run out of Lamias. The Ghost is usually your Halqifibrax target. Your Gilgamesh targets are almost always Ragnarok and Apocalypse, unless you want a crazy pendulum summon play I guess. The dragon shrines are all for dumping Destrudo, which is a free extender. It can be used to make Dragster, Alexander, or Halq in a pinch, although you do have to be careful not to burn yourself out. I'm choosing to main deck Eternal Darkness, because I think the lock is a bit better than Patent License, but you can side Eternal Darkness out for it if that's better. The side deck and hand traps are flexible of course, but I think these are pretty good for this format. Enjoy!
