Using. Oh my god this team is fun. I'm using the base team with some of the suggestions that Cherub made right now. It's beastly. And you're so right about Darkrai. I haven't had a single real Uber player NOT swap immediately, and the Dark/Fighting as coverage, you hit pretty much the entire Tier.

Also, running the extra Attack on Gene is amazing. A ton of things in Ubers have high Special Defense, and many of them have the Psychic type too.

I may look into Iron Head too, but not seeing so many Terrorakion, and the Kyurem Forms go down easy to Kyogre.

This team is montrous, and, as a brand new Ubers player, I now have an 8/3 record, with the losses (other than the very first match lol) were to the same player. I love it! I wish I could duplicate this team style to other tiers, but nothing works like Darkrai or EKiller lol.

Edit for update:

Sitting at rank 17 on the ladder right now with a 28/7 record. Only having lost to a few haxy matches, or missing that crucial OHKO/Sleep with Darkrai, or just being outplayed in general, which has happened about 3 times. Always a close match though on those losses, which is good for me. (2 of the losses were to a Top 10 ranked member though, Rank 4 at the time.)

Trying Roar on Groudon right now. It's actually very nice, but Groudon seems to be my go-to Blazekin check at the moment. Folks seem to like putting up a Protect, which makes for an easy switch, takes that HJK or whatever they want and OHKOs back with EQ. I set up rocks all right, because nothing can really OHKO Groudon without hax or a lucky switch, so Rocks go up, Groudon either goes down swinging with EQ, or swap in to something more fun.

Genesect is my swapper. If I lose ANYTHING, Gene comes out for a UTurn, and out comes the proper pokemon. It's a nice bluff, considering, if Darkrai is down already and Mewtwo isn't, Gene takes it out no issues. Running 100 Atk/156 SpA because that OHKO on Mewtwo/Latias wins matches.

Everything else looks fine though. I am debating Specs > Scarf on Kyogre, but the speed is phenomenal, so it will probably stay Scarf.

But basically, as long as I can keep ekiller and Rayquaza off the field til there's only a couple pokes left, or at least a team full of battered fighters, Arceus especially goes to town on them, usually even having enough bulk to set up a SD and destroy everything.
