For everyone that sees this spell as a tutor for Hadronox: remember that this expansion will give us a lot of anti-combo tools. In particular, we'll now have Saronite Taskmaster to mess Hadronox's resurrect pool, which may not be as efficient as before.
Instead, let's look at this card from a Beast-Druid point of view; moreover, we haven't see the Loa yet, so who knows maybe it will justify this archetype even more
Not to mention if you want to tutor Hadronox for 4 mana, you just play Psychmelon instead.
This looks like a strictly aggro card to me. If you can build a board quickly (which with a 1 mana 2/3, you can), you can easily kill the 0/3 taunt and it shouldn't set you back too much. The only really bad thing is if this guy is on a wide board and your opponent clears the whole board and get a free taunt.
Even if combo decks are meta, you'd play Demonic Project, Dirty Rat, and Gnomeferatu instead. 8 mana "do nothing" against any deck other than combo is useless. This card will not see any competitive play.
