Hmm, a Farfetch'd and a Venusaur. The latter is tempting, but since I've already got Switchblade, my male Sceptile, I'm going to avoid the tempation to catch the Venusaur. As for the Farfetch'd, if I find it wants to battle, I'll defend myself by sending out Dynamo, my male Electabuzz, having him use a Psychic + Thunderpunch combo to slam the bird Pokemon into the ground, close enough for the electrifying punch. However, if the Farfetch'd doesn't want to battle me, that's fine enough; either way, I'll keep going afterward with Tyranno still keeping an eye out for any Pokemon above me that are out of my view.
