EV training for countless hours, normally gets me about 3 or 4 in whatever I am training. If not an action replay when available, or trading.
Never really cared for shiny Pokemon though, normally they go up for trade so I can get something worth keeping.
Thats strange because i walk around in grass all the time and i have only found 1 shiny pokemon in the grass ever and that was a bidoof lol so ya like i said in one of my other posts my main way of getting pokemon is through tradingI just run around in grassy areas. I've found that to be a strangely effective way of running into them, as they seem to pop up when I'm not even looking for them. I've never found a shiny with the Poke Radar but I've encountered at least five just walking around.
