For such a big spell in WOW, the effect sure is underwhelming.

Garbage

Can easily complete the quest with Soulbound Ashtongue.

Does it hurt having such an enormous brain?

I made a Preist card called Apotheosis once. I made it legendary since an Apotheosis is something of a Divine Ascension to the highest plane of existance. This is just so plain. Also, yes, I do know of a Slay the Spire card of the same name.  

When are indie companies gonna stop copying each other's work?

The line between inspiration and plagiarism is thin in this one.

Super strong card, its almost a little Zilliax buff without DS & Taunt but for 2 Mana less and playable on EVERY minion

A bit like that one result from Unidentified Elixir, but with +1 more health. Also a good card in Slay the Spire.

Another man of culture?

I immediately thought of this too, but the art looks really similar to be honest. It's a bit suspicious.

To be fair, the Hearthstone card is based on WoW's talent, so if anything it's probably Slay the Spire's artist who took inspiration form WoW.
