It's like a Nuzlocke but every caught Pokemon is to be Wondertraded.

I kept Treecko because I want to use Post-game (breeding etc.)

Also I have put myself a few exceptions and other constrains - Legendary Pokemon are not to be traded.

Limited Team. Putting away the strongest Team-Member after a major battle (that's what happend to Treecko... it didn't die, it swept away Roxanne and was the strongest with Level 15 )

Keeping to your own rules is hard but will give you quiet the tale to remember and tell about.
