what sort of rare 20s? good nature ones? yeah game is all about the trading/ecconomy
my first eevee was adamant, so i made a whole new character just to get a better nature, and lucked out with timid! (can speed run it int his game in like 30 minutes)
I made myself a full ev'd modest kingdra, and timid jolteon. 2 of the best competitive pokemon you can get, from what I can tell. also got my hands on a jolly crobat and modest blastoise, which could be competitive.
but half the TM's I need aren't implemented yet so im kind of screwed (thunderbolt etc.). I wanted to start on some 3v3 lvl 50 competitive.
