It just occoured to me that this might be a sort of busted. I think many of us have lost to
The Number Must be Few, but you can't really build around that card, it's rather just a meta hate.
On the other hand exhausting the ring bearer in expanded is fairly simple (
Isengard Ruined +
Saruman, SoS +
Gollum, DaD already gets there in most cases), then you can play
Treacherous Little Toad with
Deceit backup and just sit back. The move limit bonuses are for the entire turn, so even if your opponent can discard
Traitor's Voice in the fellowship phase, it's still there, and you can replay another copy in your shadow phase.
Just throwing it out there in case if someone wants to experiment around with it.
