One Per Challenge

[Raviel the Phantom]

So I have seen the MonoType and MonoGen challenges, but there is one idea that works well that I do not think many have tried. Try playing reborn, but only allow one Pokemon per generation in your team at any time. So only one Gen I, one Gen II, one Gen III, etc.

2: All Pokemon, both in your PC and your Party, are of that one Generation. Even HM slaves. Exceptions are:
A. Pokemon needed in order to get a Pokemon of your Generation (using Reborn as an example, Carnivine is allowed in a 5th Gen run so you can trade to get Tynamo)
B. Pokemon who are obtained as part of the main story and can't be avoided (Like the Ponyta in the Magma/Aqua gang quest). These Pokemon are to be released as soon as you're done with them.
C. Pokemon who evolve into, but not out of the unused generation (For example, if you already have a Gen 2, Magby is allowed so that it can evolve into Magmar, or even Magmortar if you don't have a Gen 4.)
F. In Reborn, if you really want that Experience Share, then sure you can buy the caged Pokemon for it. But you have to release all the ones not of your generation when you're done.

3. If you happen to accidentally get a Pokemon not of your generation and it isn't story required, you have a penalty: Soft reset right then and there, no matter how much progress you lose from it.
