How about this:
I want these 2 Ev trained:
Clam non-shiny Regice: (desired IVs: 252 HP / 252 Def / 4 SpD)
Shiny Timid Kyogre: (Desired IVs: 252 speed, 252 sp. attack, 4 HP)
They're both freely distributable, so it's okay if you keep a copy of what you EV train.
I'd be willing to trade you the shiny Regice upfront if you'd also EV train that for me and get me a copy of it - trading me all 3 for Swampert. Does this sound fair?
