My friend (CuDi` from Pojo) topped a Regionals with a Cat Synchro deck. A lot of the people I saw thought this deck was pretty excellent. I performed well consistently throughout the whole day and I think it would be viable for this format as well. He's already performed an update to this deck, using the new Super-Mega Nimble Hamster to replace his lost Chaos Sorcerer.

An Analysis.
I feel that overall, this deck is really solid. The only cards I possibly don't like are Giant Trunade and Smashing. However, with this deck's great OTK abilities, I think these cards can allow for easy wins so they might be justified. If I were playing this deck, I would probably go with Book of Moon over a Smashing and probably some more defensive Traps (Roars against Glads?)
