Hey, something we agree on.
I was playing a Renolock with Patron Warrior, and I had a board of:
Kel'Thuzad
Unstable Ghoul
Grim Patron
Grim Patron
Grim Patron
Plus a Death's Bite in my hand.
He's down to 11 life, so I think "Even if he drops Reno, I don't really care". I also had Ysera in my hand, so I knew I could out-value him (I know, my Grim Patron deck is really weird, but I went 6-3 with it today at rank 5!).
He drops Sylvannas, Shadowflame's the board, and steals Kel'Thuzad, who resurrects Sylvannas.
Spams "Thank you" and "That was a mistake" for a good 30 seconds before finishing his turn.
So I drop Grommash, hit face with the Death's Bite, the whirlwind enrages Grom, and end him. I made sure to give a "Well played" as his portrait exploded.
