Further question:Is Red Jephthah a cost-benefit ability? If so, why? (See Haman's Plot/Gallows)
IMO, even at face value he seems like a backwards-worded cost-benefit. You can discard the characters if you discard the top card of your deck. You have to discard from deck in order to discard the ECs, so it certainly sounds like a cost-benefit.
On the original question...I'm not sure that there is any rule stopping you from using both, honestly. Can anyone point to a reason that wouldn't work?
Slight variation in question.So if I have a 150 card deck with 6 Jepthahs, 3 of each, and each one is discarded at some point am I allowed to use the ability from each Jepthah or just one of each?
