U need to keep your togekiss healthy,if u see a pinsir around... And good team I like megagross + manaphy...I don't run Hammer arm because of its accuracy, taking Iron Barb/Rough Skin/ Rocky Helmet Damage, and the speed drop (which would force me to switch out). Togekiss is my Mega Pinsir Counter because Pinsir because Pinsir can't kill it unless it uses SD. I had Grass knot, but Substitute turned out to be much more useful because I could use it on Rotom-W and other status move users, and then kill them.
