Another great show, guys.
Inspired Flamespeaker's ability first appeared on Elkin Bottle back in Ice Age. We first put it on a red card in Magic 2014 with Chandra, Pyromaster.
Er, what about Elkin Lair?
EDIT: I guess that card is a little different, since it sends a card from your hand into exile instead of the top of your library. Nevermind, I guess Pyromaster is the first time. That seems awfully late in time, though...
EDIT2: I'm mulling over your comments on Dakra Mystic, and I disagree with you. This card is potentially very good for the same reason that Deathrite Shaman is good - it's practically a one-mana planeswalker. It has a cheap activated ability which can do a variety of different things depending on the circumstances.
In the early game, you can use it to accelerate you and gain card advantage. If you ever see an enemy bomb, you mill it, but otherwise just keep drawing cards faster. This alone magnifies the advantage of decks running power, who can put those cards to use immediately.
Kevin touched on a critical point that you both undersold - you get access to the sorcery speed cards first. So, if you have a deck running Duress / Thoughtseize, you don't care too much if your opponent gets something useful; you're gonna to strip it out of their hand before they can cast it. Heck, imagine this play:
"End step, tap Dakra. I see Cabal Therapy. You see <<something awesome>>. Okay, lets draw. My turn, Cabal Therapy naming the awesome card I saw your draw and looking at the rest of your hand. Oh, you have something critical in there that is about to kill me? Sac mystic to therapy away the other bad card."
In mid or late game, I think Dakra's role shifts from accelerating you into controlling the opponent. It's true that Dakra is worse than Jace in a situation where you push them past a bad card. But, remember, you're seeing half of the cards they draw and getting a choice about them. In a format full of singletons, that choice matters. They're only half as likely to topdeck a restricted bomb while you're hitting them with Mystic.
So, contrary to what you're saying, I see Dakra being very valuable in kind of a mid-rangey merfolk or BUG deck. Turn 1 duress, turn 2 mystic, turn 3 go to valuetown is a fine start.
EDIT3: Finished the podcast. Great job as always! I think Kevin is spot on about Disciple of Deceit. It'll be slow to adopt but people will try it.
One more comment: you did not cover Kruphix' Insight. As a three casting cost card that potentially draws you three cards while showing you six, and having astounding synergy with Animate Dead effects, this is another potential role-player.
