First of all, Darkrai is weak to fighting type moves, so you have the advantage there. I'd recommend bringing along a few X-eye seeds to keep him occupied while you take out the other Pokemon, and then you can focus on him. Also bring along a few reviver seeds in case the unexpected happens.
It's the Darkrai battle, as also seen in Pokemon Mystery Dungeon Explorers of Time/Darkness.
You have to beat the game to battle darkrai.
