The most insane arena game ending I've probably ever had (2000+ games).
A three picture story. @ 9:1
Rogue plays Deathwing to wipe out entire board. The Force Tank was his, rest of cards were mine (Minus the Pirate and 1/7 taunt from his hand). I begin to hover my mouse over the conceed....

Top decked BGH....

He quit the next turn.
I don't think I'll ever have another arena game where someone plays Deathwing to wipe my 5 minions off the board only to have me top deck BGH on a class that has almost no hard remove aside from 2 card combos in order to regain control of the board. Was awesome
