...A new type of challenge that is purposefully harsh, but gives a second chance for your fallen pokemon, in exchange for something much more important.
It starts off like many challenges before. Choose starter based on last digit of OT, 1-3:water, 4-6:fire, 7-9: water, 0:your choice.
You can only catch first pokemon you encounter on the route. (must nickname, dupes clause applies.) You must set battle style to SET. Battles are harsh, other trainers wont stop attacking because you switched, and wont even stop if you have no pokemon!
You can use pokecenters as much as you want and buy any items you want. Gift pokemon cannot be recieved, nor in game trades.
Any pokemon caught with a full party are dead, they rot away in the box and die of starvation and neglect.
