In regards to trading for the Poliwag with Drizzle. I have pretty much all of Gen 5 pokemon. I have an Exeggcute with harvest from the DW. I have a Ponyta with Flame Body from DW. I have lot of the starters from previous gens. I have Zorua, Buneary, Skitty, Smeargle, Heracross, Musharna, Horsea, Ferroseed (with leech seed), and Spiritomb and others.
I would like to trade for a female poliwag with drizzle. I have a lot of stuff trade but nothing on your list that I see. I hope we can work something out.
