I think the big 5 will be reshiboar, zekdonk, donchamp, lostgar and magnegatr. but honestly, there are so many decks with so much potential in this new rotation. I'm so excited
however, I don't think straight cinccino will do very well. jumccino will do good but cinccino alone can't compare to any of the big 5. they just have too much hp. and by turn 1 to get evolved to cinccino, they're have noticed your plan with minccino being out, and they'll put a bunch of pokemon out so they don't get T2 donked....(but then you throw out jumpluff and they're stuck :] which is why you need jumccino)
