Not sure if Nightmare and Vortex fit so well. For one, Vortex have a top poisoner, but Nightmare have their own selection of poisoners. Artus is also problematic: Vortex is a clan with a Defeat bonus. That means you want to maximize your winners in your other half. I wouldn't play a DR that can't win like Artus with Vortex. Third, Vortex want to partner with a clan that can provide strong characters to anchor the 4th round: the Vortex bonus is useless on the last round. However, SOB is often negated on the last round as well (for instance: against Vortex!). SOB often doesn't give you a benefit on the last round, which means they pair poorly with Vortex.
Solid, play safe, nothing spectacular. Put a Kenny or Cutey here might be more interesting.
Agh, I give up. Time to take a break from ELO with Nightmare. With the permabanning of Azel I don't think they're as effective for creating gaps unless I want to give up stars for Karrion.
Nightmare is not bad, thing is you have to choose the right cards to make a half deck. when using nightmare, you will probably be trying to win 2 rounds, (due to cards like artus and cutey and kenny cr). that said, people often find cutey and kenny cr kind of hard to use with their 6 power. then, edwin and pan is used.
nightmare works very very well with uppers, just saying. nightmare gheist is annoying as hell too
I know nightmare is still very playable but they don't fit in with my current playstyle. I'm just going to experiment for now.
