Keldeo is a Water & Fighting type, and I think is associated with the Swords of Justice, but I don't remember if Keldeo is actually a part of that group too or not. Anyways, Keldeo has an amazing design, both in regular form & resolute form, I tend to prefer the regular design though over the resolute design. Keldeo, both in regular & resolute form, is great in competitive as it has nice stats, nice movepool & decent abilities. Now, I'm not sure if Keldeo is the best out there, but it's definitely a good one to use. Overall, I love Keldeo so much, but I was close to not putting this in my top 10, so I chose to rank it 10th.
