Dipplin & Teal Mask Ogrepon ex

With this deck, 9.5 times out of 10 you can draw 1 or 2 basic pokemon to start. With Hero's Cape, Dipplin can function more as a real ex Pokemon, along with chip healing from Radiant Tsareena. While there are no Rillaboom for Thwackey to evolve into, it still plays a vital role in a match with it's Boom Boom Groove Ability, and Festival Grounds dosen't even need to be active for it to work, so you could use it to actually search for Festival Grounds. And if that dosen't work, you still have Sawsbuck

And if that dosen't work, you still have Sawsbuck to look through your deck for it, since there is a high chance that at least one is in your deck. Both of these cards can be put up easily by combining Nest Ball and Jacq together. Teal Mask Ogrepon ex and Blissey ex, plus Bug Catching Set and Energy Switch, can be used to immediately power up Dipplin and more Pokemon in play, so don't sell them too short either. All in all, there are many different directions that this deck can go in if you can adapt to your starting hand accordingly, and with Roseanne's Backup and Cyllene, there's always a chance to turn the match around in your favor if things go wrong.
