Well, that Cherrim thread went away...I guess that answered my question in it...
Anyways, along with the recent Dusknoir love from SF, today's CotD is actually a promo that's fairly useful. 130 HP is average for a Stage 2, +30 Weakness to :dark: is good since it is an underplayed type, a -20 Resistance to :colorless (ok, since :colorless Pokemon are around) and costs a reasonable :colorless:colorless to Retreat. Dark Hide is a fun Poke-Power; it lets you not only see your opponent's hand (with a Heads flip), but also lets you take a Pokemon you find there and send it to the bottom of your opponent's deck. Spirit Pulse does a good 70 for
sychic:
sychic::colorless, and lets you move up to 2 damage counters on Dusknoir to one of your opponent's benched Pokemon.
So, how does this one compare to the others? Well, first of all, this one should be used only within a Dusknoir-based deck; it's not a great one to tech in, like Dusknoir DP. SF gives us another 2 Dusknoirs (plus a Lv X), both of which are also good; #1 has a great Poke-Power also (letting you potentially avoid playing Claydol) and Count Even can be a good attack (Night Spin is overpriced, but can stall nicely vs decks like Kingdra). #17 also boasts a nice Poke-Body (letting you place 1 damage counter on any of your opponent's Pokemon that have Energies attached, if Dusknoir is active) and Dark Mist hits reasonably hard if your opponent's Defending Pokemon has at least 2 damage counters. And of course, you must play at least 1 Lv X. Overall, I guess it boils down to what you want the deck to do; likely, I'd play 2 #1 SFs and probably 1 DP, since the DP does have (imo) a better Power. If you're more into spread-oriented, #17 SF aids in that. So yeah...up to you, lol.
Modified - 8/10 (A solid choice for a Dusknoir deck, if you don't like DP or SF #17)
Limited - 0/10 (Since he's a promo, you can't use him in any limited events)
Unlimited - 1/10 (No real use here)
