Problem

Ok, so the problem is that Void Contract's (The new 8 mana epic spell for Warlock) Flavour text is "YOU SIGNED WHAT!?"

In case you don't know, Void Contract Halves each player's decks.
Sounds a lot like a purple friend we know.

Solution
I want to get enough community recognition that blizzard changes the text into some sort of thanos reference, I've made a few lines that could work *AHEM*

Jeklik: “Did you do it?”
Gul'dan: “Yes.”
Jeklik: “What did it cost?”
Gul'dan: “8 mana.”

Fun isn’t something one considers when halving the decks. But this… does put a smile on my face.

You Should've aimed for the hand.

When I’m done, half of each deck will still exist. Perfectly balanced, as all things should be. 

Just a few recommendations which I think are great, but by all means feel free to come up with your own.
