We're bringing back spell hunter in a big way. Especially with the unnerfed/buffed core set cards this looks very nice to play. i.e. tracking. 

Since the trickster worked previously, I can see this also seeing play in a spell orientated deck. 

Holy Synergy works well for paladin. 

Zoo, Egg, Face, Win. 

Deathrattle Demon Hunter? Nice. 

Holy spell synergy, as well as the ability to swarm the board. Works well with the new Holy Spell Synergy legendary also. 

Enter the Cannons! I love this card, and the secret synergy is just another bonus - as well as board presence. Just watch out for silence. 

I'll be honest, it doesn't impress me. 

Murloc Shaman is back !

Nice idea for weapon control decks. 

I think this will only be useful at later ranks, as early game it is too weak. 

Frost Nova plus, very nice freeze synergy. 

Its great to see kazakus back, with a similar effect to previously. Will for sure see play. 

Murloc tribal board clear is a very nice thought, especially for generation. 

It is a quite strange card, but if you're playing weapon rogue - then the hero power replacement where you don't want to replace your weapon is very useful. 

Not really Anti-Secret, but the knowledge and tempo gained vs a secret deck will be exceptional. 

Hero power mage is Back! 

Hero power mage is Back! Also hero power Odd Wild Mage is looking strong. 

I'm loving the idea of spell hunter using this. 

A very good card, these sigils seem to be quite potent.
