I think this quest is just too quick to complete and there's not much you can do about it, unless you're playing a deck with wide boards. I tried Handlock but all my minons were always frozen and I couldn't even do any damage...
It's too early to call it overpowered, but it seems... a bit problematic.

I removed Zilliax Deluxe 3000 and put Sif in their place, feels better another kill condition, this deck can already generate a lot of armor and life

Fun deck but very inconsistent, most games you're gonna be dead before you even get 7 mana
I made a few changes to try survive the early game still experimenting.
Removed Guff Runetotem Feel like this card is being wasted as tempo and too greedy
Living Seed Good card but I feel you're dead if waiting for this to activate
Soul of the Forest Not needed, most boards cannot deal with your stuff and if they can it'll just be another lose
Added - Meeting Stone A body with some generation
Thorngrowth Sentries Just bodies to soak up damage
Imprisoned Satyr Another body but as the potential to reduce one of your minions
C'Thun, the Shattered If you get your combo going you can easily draw your entire deck, just another win condition
