I used to be a pretty prolific shiny hunter back in the days of Gen IV and V. I still dip back into it every now and then when I'm particularly bored. The latest shiny I've found is a shiny Torchic by SRing in Omega Ruby, and it wasn't a particularly long hunt either; maybe like 150 to 200 SRs at most.
150 - 200 SRs got me like/// O_O
I got 2 shinies in a row on X. I was hatching eggs when I accidently went into the grass and encountered a shiny Psyduck in a horde battle. A few minutes after I hatched a shiny froakie ^.^
I had something like that happen to me in Platinum. I caught a shiny Spearow on Route 225 and decided to EV train it on Route 226. When I started running through the grass there, the first Pokemon that showed up was a shiny Raticate.![]()
