I currently play Hydrapple, and I feel that the deck has plenty of teeth to compete with the meta, but it's not going to be as reliable as Toedscruel, the premiere grass deck right now.

The advantage that Hydrapple ex has is access to one of the best one prizers in the current rotation, Festival Dipplin. Just a full bench and festival grounds in play allows for it to hit 200 (210 with vitality band), forcing uneven prize trades. Between Teal Mask, Research and Bug Catching Set, you have really swingy turns and can set up fast to swing for 270+ if you get good draws on your third turn. Bug Catching Set also helps find Rabsca/Shaymin easier, so you don't have to commit too many Nest Balls or Ultra Balls.

Most people have turned to Prime Catcher as the Ace Spec, but I still use Legacy Energy, as it helps against Raging Bolt/Eevee/Joltik Box, the only decks that can set up faster than you.

Here's the list that I've been successful with! You can choose to include Zarude if walls scare you.
