Ok, I think I have it now. How about this?

@McF4rston

The flavor of your twinspells... I just love it (btw, is that Eldar at the second one?)

However I'm kind of confused with Blacktalon Agent. If you play one, next one you draw is summoned instead of you being able to trigger the battlecry, right? Then its Reprise only casts when drawn, so if I play one with another one in hand I can get the battlecry, right? Not sure if having the whole class working on replicating stuff this might be too strong. I know it's no Flik Skyshiv, but still not sure. Maybe it's fine as it is.

Really interesting, I must say. I could see buff on Sleeping Dart. Assasinate costs the same and removes the minion so it can't get taunt or silence, or annoy random effects. Also... not sure about the synergy between this and divine shield, although it seems it does not prevent the can't attack effect to happen. Not a fan of rush cards in Un'Goro set, but won't make a big deal about it. Btw, does Tea Time heal your hero whenever its channel is triggered?

@Anatomy_of_Time

I like this stuff. Can't remember now if the nymph could somehow perform several attacks in a turn, but this card sure opens to possibilities.

P.D.: Is'nt it funny? We kinda predicted one of this next expansion's new mechanics, cross cards.

Looks pretty good overall. The C'Thun parts and the Bounce cards especially look great. Light of Tomorrow is really cool.

With Fist of the Heavens, it's spelled "lose 1 Durability."  I also might be missing something because I'm not sure why it has that decaying Durability bit in the first place.  I understand the doubling can be powerful, but the class doesn't have any Durability buffing so it would seem cleaner to just be a 1 Durability weapon, rather than a 2 Durability weapon you can only use one time.

@Klipce

Wanna start by saying that I really like the effect of the Quest Spell.  I've had a draft Rogue Quest with "Draw your deck's last card" as the trigger condition, but I could never think of a good reward.  You nailed a cool and flavorful one.

That being said, I have the same critique of this that I had of the Nymph's potential Start of Game effects: This is a build around card, but the class cards don't have a lot of tools to help actually build around it.  In this case, in order to get the best payoff from this you'd want a deck with both Discover-enablers, and also one that draws a lot of cards so that you actually get to the Fatigue phase.  However, there's only a few Discover cards between the Pioneer and Un'Goro sets (and one of those is a conditional Discover), and the main card drawing is Foretelling. I suppose Zandalari Explosion also helps to thin out the deck (and this IS the expansion with Hemet, Jungle Hunter), but suffice to say that the amount of games where you'll both be able to finish the Quest and cast the reward and enjoy the benefits of the reward would probably be in the minority (just like in the normal game the odds of actually hitting Fatigue are in the minority, and the odds of drawing Fatigue 10 times even smaller than that).

But, after thinking over my Gnarlroot comments, I realize I'm probably being too precious and holistic with my thoughts.  For the purposes of the competition having cool and flashy ideas may be more helpful than whether the rest of the hypothetical set could be useful in a deck.  As I said at the start, in a vacuum its a great and flavorful Quest and reward, and I'm sure people would appreciate it.

@McF4rtson

Very cool overall, and I like the time flavoring. Any particular reason The Transient Knife only affects Kunais and not a general "your weapons"?

Blacktalon Agent is a bit of a headscratcher, as I have some of the same questions as Mvon. It feels like a card pushing you to have one-of and then duplicate, since the Reprise effect is a bit of a downside.

This challenge is someone from another class working on class cards. I know it kinda is stretching it a bit, but it's pretty much the closest I've seen by now to that (beside Gadgetzan tri-class)

Quote from Klipce >>

Just saw the feedback on my quest reward as I was about to finish my final post and I have to agree that it is a bit clunky and not hard to build around... So let's rework it ! I came up with a few options but I don't know which one is best.

Each takes a different direction. #1 is more value oriented but it seems a bit weak to me. #2 is a bit crazy and I like that but maybe a bit boring. #3 is cool but it's not swingy at all.

The thing is, Un'Goro quest rewards were both simple and game-changing, which I want to replicate. Each of them interacted with a different part of the game and since Fatigue wasn't touched on yet I figured it would be a good design space but I forgot that bringing you deck to fatigue requires heavy deckbuilding which can overshadow the quest it self.

So yeah here are my options, I'm currently going back and forth between #2 and #3. What do you think ?

 I'd also suggest #1 or #2.  #3 feels like another anti-Fatigue/game time extender card, ala Archbishop Benedictus, and he rarely saw much play. 

For #1 I'd go with the Cost-reduction suggestion.

For #2 I think you'd want to drop the cost to (3) or so.  Keep in mind that you'd be spending the (5) mana to discover the other reward and then usually an additional (5) to actually play the final reward.
