New Warlock Spell - Unstable Felbolt

In very early turns of the game, warlocks would currently use mortal coils and kobold librarians to contest the board. Is this better? I'm leaning on no, just because it is so poor against decks that do not demand very early interaction.

Good on an empty board, otherwise crap.Soulfire is better in every way. 

Maybe in a handlock that has no early minions or Egg-lock but there are some better activators for Eggs if you ask me.

Well, that doesn't mean i won't try even the shittiest card if i have them in my collection tho.

Good for controlling board, especially for control decks that focus on removal. Will see a little play, i think.

Playable, but only in control.

I already hate playing against this card. Seems pretty annoying on its own on an empty warlock board. But knowing All the gambits and expoits Gul'dan can go for from time to time...

I think its a good card and will have potential. 

This card cannot really be played in a zoo/midrange type deck because it is just too taxing on your board. But I do think this card has potential in either a control deck that doesn't play a lot of minions in the early game, or in an egg deck that wants its minions to die.

Not that great I’d say, would probably want to run other cards over this one

Very strong if used with no minions in play, and still good if it hits a friendly one regardless.

A worse Holy Smite that becomes holy smite on empty board. I feel like warlock has some better control tools than this.
