I'm definitely excited to see Delphox and its break, even though it'll still be outclassed by Greninja and trevenant in terms of consistency and ability to mess with the current meta. The Ho-oh break is less than desirable, and it'll just be another mediocre promo to add to the collection. The same goes for Crobat; its attack is a horrible mockery of deck and cover, one that will never see much competitive success, if any at all. Mega garcomp is fairly hype though; with double dragon energy, mega turbo, and hoopa, getting a turn two 180 is entirely reachable. Aromatisse/ fairy drop will be able to keep chomp fairly healthy for reliable damage output as well. The only problem is that with hard hitting, cheap basics running amock in the current format, Big G will be a lot less viable. So what if you can get a turn two, or even turn one, Crimson Edge off on a joltik? Another would just take its place next turn. Your only hope would be to rely on chomp's inherit tankiness and spam healing cards to try and stem the marching tide.
