New Neutral Minion - Talented Arcanist

With even cheaper cheap mage spells, you'll burn through your whole deck AND kill the enemy

Rogue can use it. Great for combo setups.

[Hearthstone Card (Celestial Emmisary) Not Found], you are back. With more stats and Neutral. How weird that this card exists.

Celestial Emissary saw no play and, aside from competing with Ethereal Augmerchant in Lifesteal OTK DH, i don't see any other use for this card, especially considering Talented Arcanist is more expensive. Sure, Skull of Gul'dan nullifies the mana issue, but still.

Cheap way to end a game if you have the damage in hand.

A great way to get rid of a big board too.

If you said this is only good in Mage, you should probably go ahead and uninstall Hearthstone.

Every damage-based AoE in the game* wants to follow this card, as do most single-target burns -- especially the ones that can hit face. Burn Shaman in particular will absolutely be playing this.

*excluding Warrior shenanigans in some cases

Reprint of Celestial Emissary. Won't see play.

The classes that care about spell damage already have efficient spell damage cards like Imprisoned Phoenix that isn't limited to one spell. I think Talented Arcanist doesn't do enough for any class to run it.

So clunky to make use in a spell damage deck

Versatile and simple to slip in to almost any turn. Gotta get a good payoff, though, since the minion itself is subpar. 

very good boost 

Not strong enough tbh. the +2 spell damage dormant minion in mage and shaman is probably better for a combo deck

Celestial Emissary 2.0. Kinda meh 

I think this will not see play

Can be good with cheap AoE spells, but as Celestial Emissary, won't see play.

Quite a number of reprints we've got in this expansion.

Ok for Mage i guess but everything else ... pretty meh!

I'm looking at you, mage

Good potential
