Thanks, but I never usually trade other people's pokemon (I barely trade my own as well) :P
OMG! WZ you're a liar! I just successfully captured Great Marsh Yanma on my Pt retail cart! It was time consuming, but it's easy. Here's what I did: I saved before paying to get in with a repel in effect and my syncer up front. I hit my seed, went in, and rushed to the grass patch then pressed X. Then I sweet scented and looked at what frame I hit. I got frame 16. So then I needed to find out how many frames the NPCs advanced. My starting frame would be 3 because I start on frame 1, Sweet S advances by 1, and stepping into the grass advances by 1. 16-3 is 13 so the NPCs advanced by 13. My target was 23, so I needed 5 journal flips (23-13 is 10, 10/2 is 5). I hit my seed again, did 5 journal flips, went in the Great Marsh and sweet scented and I got my Yanma! :D
Btw, Jk about you being a liar, you said it was almost impossible.
