I have a hacked lv.100 Sceptile which knows Slam, Detect, X-Scissor, and Leaf Storm.
I also have a hacked lv. 94 Milotic that is a great defense wall, that knows Dragon Pulse, Double Team, Toxic, and Light Screen. I'll give you either one for the Darkrai. PS: The movesets are pretty horrible but remember all you need is 3 heart scales cause each one of these pokemon have move worth keeping. Hit me up.
