Honchkrow is easily one of my most favorite Pokemon, so I did this to work well with him.

From my experience, almost everything Honchkrow can handle will switch out for fear of sucker punch, and since it requires the foe to attack you to work, they essentially get a free switch out of you. You could use Pursuit, but it limits you since it's not powerful enough to take out some essential targets without them switching out, and if you want another STAB move, you severely limit what he can cover. This tries to use honchkrow's dependability on the opponent's movements to his advantage. Send him out against a Pokemon you know will switch out with. Once it switches out, use Tailwind to double his speed. It makes him dangerously powerful, and with 530 speed (using a speed nature) not even Deoxys-S can outspeed him without a boost of its own. However, he's the only Pokemon that can if you give him an attack nature. You should watch out for enemies in his tier with speed boost, such as Yanmega, Combusken, Ninjask and Sharpedo, for fear of their outspeeding him. If your opponent has priority, you can answer back with sucker punch. Brave bird gives him an extra bit of power, while superpower's stat drops won't bother him since he'll switch out once Tailwind wears off. You could use this with moxie, but I wouldn't really recommend it from testing. Also note that he can't learn Superpower with his DW ability.
