They really did kill Tengu Plant decks this format. What more to make Xyzs even stronger then kill one of the most popular Synchro decks?
Even so, I still prefer to use my Crashbug deck simply for the fact it is not overpowered this format. (Heck, once it gets Tour Guides in the Battle Pack, it still wouldn't be too strong. Six Samurais and Inzektors still would eat it up. Thank god for Dark Armed Dragon.)
