Something that worries me is that I fear we're making of CAP5 to good a Keldeo partner. Something which can effortlessly get Lati@s and Jellicent out of the way is quite amazing for Keldeo, and if people resort to things like Dragonite to counter it, well, we've just increased the usage of Dragons.
Therefore, giving CAP5 an ability that can work out , even partially like Harvest, in the rain seems dangerous to me.
I much prefer Chlorophyll, but I don't quite grasp the point of not using Flower Gift. Sure, it artificially increases our BST, but isn't Chlorophyll doing the same? Moreover, being able to outspeed Specstios is great but unless we sack something to get a clean rk, we need to come in and weather a full-powered Draco Meteor, which is almost impossible without heavily balancing our stat spread. And Chlorophyll doesn't give a hand to stomach the various attacks we take on the switch from anyway (most probably) slower pokes, such as Jellicent.
Finally, the increased SpA, while not making Pursuit any stronger, could make certain threats who would force us out right when they come in think twice before entering for free, thus helping us keeping a bit of momentum.
