Alright so as of right now:
-No items in any major battle (so I assume rivals, gym leaders, Giovanni, E4)
-Must use all in game trades in a gym battle (Nuzlocke style first per route):
-Abra for Mr. Mime
-Poliwhirl for Jynx
-Slowbro for Lickitung
-One of Raichu/Venonat/Ponyta for electrode/Tangela/seel
-And no resists/super effective moves or Pokemon for Misty (ouch).
All three accepted! Feel free to keep making suggestions.
