Azumarill: Ban
Azumarill on its own isnt deadly, but due to the doubles nature, once it sets up, it is really hard to bring down. Around 1/3 of my losses are because of being swept by this bunny. By all means, it should be Jirachi, its powerful partner that should have been banned, or the move belly drum, but as for this suspect, yes, Azumarill is really hard to predict at times, and can be broken if played correctly. So yes, I vote to Ban Azumarill.
