What switches into Whimsicott that we might expect to be U-Turning into? Bronzong, Tentacruel, Empoleon, Forretress, Nidoqueen/king, Crobat, Doublade, Blissey. Nearly all of these are threatened hard by Krookodile. Twice as nasty is the fact that Pursuit and the threat of Pursuit can assure that you take out things like Bronzong, which not only opens the door for Whimsicott, but also a host of other possibilities like Crobat or Mega Aero. Tentacruel is a bit trickier because it is faster than Krook, but if Whimsicott has attacked Tentacruel at least once, it should be relatively easy to get a sense for how much HP/SpD Tentacruel is running and therefore how much Speed it has committed to outrunning Krookodile. Even nicer, the best switch-ins to Krookodile are Chesnaught and Tangrowth, and offensive Whimsicott switches very nicely into each of them.
