Yeah it has been tempting to use Complexity -1 with my spare 9000 coins to bump up my ranking but 1300 range is really not something I foresee falling out of the 20000 range in the next week, so I'm holding off unless things look dire towards the end of the competition. Sure, I have no other use for coins given catching Mewtwo with no items or Great Ball happened so I may as well, but I'm just going to hoard coins for now.
