Ah, gotcha. I've been wondering why you'd request strong decks, but often with unusual specifics.
Well, you could always pair an offbeat FP/Shadow with something more mundane as backup. For example I think DW should be paired with a running FP anyway, so the strength of the FP can offset the weaknesses of DW.
The
Wormtongue is the version of Grima you have listed already. It's practically impossible to get past some companions when their gear is stacked 5 cards high, so if you can't compete with strength pumps, don't play by their rules! Incidentally
Wormtongue can cause hand clog which in turn helps your running FP.
