Dinosaurs are well-known for breaking open boards, and in the rather fun (for good and bad reasons) xyz festival event, they definitely still excel even if they have some trouble with utilizing Double Evolution Pill properly sometimes.
Due to the change in the format and lacking enough URs, I had to go with what worked, but given Dinos often use the main deck instead, they can still do their thing, but they need to have a bigger emphasis on going 2nd as a result, thus requiring the use of more board breaker cards.
The deck definitely thrives in a format where negation isn't as rampant, but still watch out for Ash Blossom and Artifact Lancea (if it somehow crops up) since those on the Misc in the GY can shut this deck down hard.
