Jirachi has been my favorite Pokémon ever since I saw the movie Jirachi Wish Maker. But there are a lot of Pokémon I consider special. Darkrai is also in my top 5. My non-legendary favorites are Togekiss and Shuckle.
OMG my friend and I have this running joke where she'll put a Miltank card somewhere, and then later when I find it I put a Shuckle card on top, the eye puts another Miltank. Baby Milank Shuckle's Miltank! Lol I'm just realizing how creepy that sounds. Happy passage birthday btw!
