The card is a tech: you simply look over one of those articles which shows the top decks and evaluate the number of cards (ideally low costed ones) it can screw up. Inner Fire and Divine Spirit are two cards this really screws. When played on 3 if you can hit one of those your opponent screams profanities.

Let's take a look shall we at current decks and see what it can do. Ultimately this card is a tech and will only see play if there's enough decks running around it can harrass properly. An example would be Inner Fire priest because hitting that or divine spirit would really be worth it.

GALAKROND CONTROL SHAMAN: yes

- Zentimo, Mutate, Earth Shock and Witchs Brew are great targets

- Dragons Pack before invoked twice is good

GALAKROND DR ROGUE: not much

- hitting faceless corrupter can be nice since it isnt always rdy to go

- necrium vial really good target (unless it counts it as unplayable if no dr on board)

GALAKROND WARRIOR: pretty good

- Scion of Ruin good target before invoked

- Bloodsworn Mercenary, Barrista, and Dragon Breeder are usually great targets at the right turn.

FACE HUNTER: awful!

- only Unleash the Hounds is a strong target.

So for these four decks we can see it will at best hit a good target only 15% or so of times. At this very moment it isnt so great a card although it can feasibly be seen as a 2 mana 4/3 if you force them to play off curve. These 4 decks may not exist on the ladder when the card is released and very possibly cards will be released in the set that it really shafts. This card will be welcome tech for Warlock should decks that play critical low cost cards arise in 2020.
