In other news, I finally made it out of Rock Tunnel with my Electric Team (Pikachu). Gyms fell fast after that, and I caught an Electabuzz, Voltorb, and Magnemite (and Zapdos the Fly Slave). This means I should be done with the challenge soon! Also I finally have a move that does neutral damage to Rock/Ground types (Electabuzz's Psychic).
Also, Thank you Dragon. Your challenge is accepted. Grabbing laptop now to start on... Metronome Challenge/Weak Run, which will also satisfy the Combined Challenge.
