hahahah well me personally i disliked cresselia:/ out of all the legends in D/P she was the weakest to me and all she did was sit in my box forever lol thats intresting iv never heard of anyone only keeping 3 pokes at a time lol but im not that into ev training, it seems like ALOT of work.
Oh lol yeah I got a level 10 Mew from the Hoenn Region from that Shiny Umbreon. I don't know is it just me or are there a lot of..Cresselia dislikers? I keep putting Giratina on Offer in the Global Terminal on my Diamond, 3-4 hours later, I get a Cresselia?? Got 6 of 'em in the last 4 days! And um..I do have an Umbreon myself, but its normal and still getting EV trained ever since I became a father to it hatching from the egg same with my Ninetales & Espeon (only have 3 as a party, half a party at a time lol)
