Indeed, The new Dusknoir Is better than the DP Empoleon.
I run a Dusknoir/Lunatone/Solrock deck. So Darkrai might have some troubles with Solrock's Power.
No. It isn't. They do completely different things, thats like saying Apples are better than Tissue Paper. You can't realistically compare the two.
if you play Dusknoir with Absol, then Ninetails will use Absol's Dark type to kill Dusknoir lol
If you put Dusknoir in a dark sleeve it will kill itself.
