Sledg and Cliff are top options. Sledg is more consistent, while Cliff is great vs DRs. But he runs the risk of being stranded with 6 power and no bonus. Pastor is a less offensive choice that I won't really take over the first two.
Confidence is confidence based.pretty similar to courage, an opponent will easily throw out their DR or SoA card.. if it were revenge, it could have been better, as its much more easy to control than confidence
Yes, Nancy relies too much on her ability I feel. Not only that, like everyone says, it's conditional and predictable. Rescue is also already very threatening and intimidating without that extra 5-7 life gapping potential.
And scrap what I said about Pastor. I finally tried him and he's really great! Definitely one of the top picks for 5 star alongside Sledg and Cliff.
