When is the dinosaur theme going to be over already!? Three days of this is too much. Come on, do something fun already like fairies or plants. Of course, with my luck, the next theme will probably just be something boring again like insects or zombies.
It's not like it will change your opponent's decks anyway. As long as Konami is an idiot and doesn't restrict the type of deck used for the event, don't expect this event to be anything other than a pretty version of Ranked.
The opponents aren't the problem, it's me. There's no dinosaur decks I like, so I just ended up using Amazoness with that trashy Grenosaurus Xyz in my extra deck. And now it's effing insects! I knew it! Time to just throw man-eater bug into something.
