Very nice! Cresselia is my favorite legendary ^_^ You get a second chance to catch Deoxys, so don't sweat it :)
Thanks! And yea, my National Dex is only at 238/720, so I've got a long long way to go before I've completed it. But I'm getting there a little at a time haha. I have a lot in Y and even more in my previous generation games, so between all of them, I'm probably pretty close. Secret bases are so much fun, aren't they?? And the contests are a lot of fun too, but gosh I wish they had made Wi-Fi contests an option. Missed opportunity there on the part of GameFreak :(
Say, what's your friend code? We should register each other. We can help with each other's Dexes and all :3
