Shoot...shouldn't have thrown away the Dittos that had good but not perfect speed. I could do it, but it'd be HP Fire 68 since the Attack IV is set at 4.
Just so you know, I only have 2 games I could teach Mimic in, so that's the most Leech Seed ready Oddish I can do for you right now.
Update: I got parents ready finally to do the original plan (31/04/31/30/31/31 Bold) so I'm going to go ahead and work that one. I'll look into doing HP Fire though.
Update2: Looks like I can use the above Poke when I get it to breed a 31/06/31/30/31/30 Fire 70 one, so I'll plan to do that.
