I seriously cannot figure out for the life of me why you wouldn't want Darkrai MD, which can be BENCHED and trigger auto-sleep, or even Darkrai GE4 which either pounds for 80 or does 40+sleep to trigger that IBT damage from Darkrai G's body.
If your argument for Darkrai (Reach Over) is that you want it to grab energy so you don't whiff on attachments, then I would counter with: increased consistency of draw engine begets fewer missed energy drops without actively tutoring the energy.
There's a convenient little card that can help increase consistency, especially when combined with other cards that help increase consistency, it's call Cla- oh, wait, you'd rather be able to feel morally superior for not using the best tools available to you. In that case, still consider Porygon 2 and 4 Volkner's, 4 Felicity's, and 2 POV/Rowans'/Cynthia's.
