um... well considering a bunch of 2 costs have 2/3 or 3/2 worth of stats it's kinda like getting a 4/5 or 5/4 on 4 mana which is ok, and if your buffing up a minion with a powerful effect or something then the buff itself could be amazing... then again who knows what you may get... Like doomsayer. 

Token beast druid?

if you have any beast, dragon, or murloc on the field it's a 4/4 for 3 which isn't that bad. i'd also imagine that 1 extra health can make a big difference when compared to shattered sun cleric. 

probably just have another 5/6 for 5 demon

his effect only happens when the game starts. After the game starts his effect activates so he wouldn't be to do the effect more than once most likely. 

so when it says "Random" does it mean from what you can have in the class being played (making it similar to discover where you can't get cards outside of your class) or can you potentially get Tirion in warrior, Velen in mage (20 damage pyroblast gg :).), Huhuran in rogue, or even Jaraxxus on anyone?

and then get killed turn 3/4 by a bunch of mechwarper decks, because having that brawl go into lategame right?

I could see this in a deck focused around Elise Starseeker. Instead of using her in a deck that stalls long enough to get the golden monkey you simply draw through your entire deck quickly to get to the legendaries faster. I mean the discard cards generally are pretty good at their mana costs if you ignore the whole discard thing so you'll probably end up establishing some sort of board presence and then be able to get out the golden monkey quickly... that said you'd probably end up with so few cards compared to your opponnents. 

how is azure drake, grim patron, and mukla's champion bad? Azure Drake is generally considered a good card for 5 mana and while the 4/4 stats aren't the best it does have spell damage which is pretty good for mages, grim patron can be alright if it survives as mage's have the fireblast , and mukla's champion can also situationally win the game depending on the state of the board. 

i'd say if you get like a 3/3 and deal 5 damage then it's about even. it's a slightly weaker fireball (4 mana) and a generic 3/3 (3 mana) which would mean it's a little less worth it than just having a fireball and a generic 3/3 minion, but in just a single card. bit worse early game but more efficient late game, then of course you can get stuff that is MUCH MUCH better

1/1 kel'thuzad that is resurrected gets resurrected at full strength.

kinda like bane of doom but a little more expensive, actually works as removal more often, and the minion is gurenteed even if you dont hit. i'd say pretty good. 

play barnes turn 4 and get a card with a really powerful effect like... Kel'thuzad and then coin out herald volaj turn 5 and have double the effect? maybe faceless priest will be viable?

Here's something funny... Renounce Darkness gets rid of the curse card. 

for the lols I decided invervate and yogg. figured it would be good for Trolden
