I have been planning on building a Greninja BREAK deck for sometime, but wasn't quite sure how it would fare post roation. As of the 2016-2017 rotation all water decks used Dive Ball and Silent Lab as staples, but that goes out of format this rotation dealing a huge blow to Greninja decks. Most Greninja decks will also lose Ace Trainer, Level Ball, and VS Seeker in the new rotation. I'm fully aware other decks will suffer from the loss of these cards as well, but all 3 were used repeatedly in competive Greninja decks. Would appreciate any feedback on how well you think Greninja will do in competitive play. Also hoping to get a few questions answered in the process. Thanks! Do any cards or Pokémon exist that have similar effects or abilities to that of Dive Ball? What strong trainer cards exist that could help water type decks in the 2018 format?
