Janos is unimpressive. Trying to play Edric Dayne, even with Lannisters, has shown me characters I have to spend gold on every round are not reliable. He's a good late game draw when you have an established economy and extra gold, but bad on the first two turns where it is very tight. He of course works a lot better if you have Tyrion out, but so a lot of other things that work better without Tyrion than Slynt does.

Levies I like; it's a Lannister Hands Judgement almost. I can think of a number of occasions where I have faced a telegraphed PttS or Tears that I couldn't stop. This does that, and helps fuel other options. I think its best place is in a Intrigue heavy deck where you can turn your stall into a permanent solution by forcing your opponent to discard the card later.
