What deck did you play and why?
I played Zombies because I told Burrito I would play them if I could not top the previous cup and I couldn't. They were really popular when I first started playing Trinity but lost it's power since. I haven't played them back then because I was trying to be a hipster but I have played against it and also watched some replays so it was fine.
What tech choices did you play? Absorouter and Rokket Synchron. Many people were playing it I think (?). It really feels bad to play but also really rewarding when you can actually use it. I have considered siding them out often but usually did not. There is also Danger Bigfoot which is the best discard fodder :3. Nothing unusual really, the list is very similar to Burrito's and he knows what he is doing.
How did you prepare for the meta, and would you change anything going forward?
All the good S/T Hate and it still is not enough right? Pendulum is also a deck. Zombies are actually pretty refined at this point being an old deck. All the combos, all the gimmicks. What changed is the players in tournaments mostly and they were not ready to out Vampire Fraulein I guess. I don't think I will play this deck again anytime soon so I don't really know how it's going to adapt the meta but it certainly will.
