Well, I gotta be honest, I've had a LOT of barnburner battles the past couple months in PvP. One that sticks out in my mind that happened just earlier this evening was with my Stunbomb team (Frosty...Kun-Lai Runt...Wolpertinger). The opponent was running Xu-Fu, Chi-Chi and Hopling.
He led with the Hopling, which did a great job against Frosty with Tongue Lash. I was surprised a bit. Those two killed each other, but Frosty got off his Blizzard, which is basically the key to the whole comp. In comes my Runt and his Xu-Fu. Deep Freeze, and I believe we both swapped pets. Wolpertinger vs. Chi-Chi...long story short, the Wolpertinger stunned Chi-Chi and Xu-Fu comes back...he gets put to Sleep, and so I end up locking those two down and effectively defeated them both with Deep Freeze and the Jackelope.
I thought his team was pretty cool, but the real reason I'm posting is it was a sweet victory over two Celestials.
