Like many other people, I've been timed out of three consecutive matches because of the Kessig Naturalist freeze.

Most recently, here's what happened:

I attacked.
The naturalist triggered, which appeared on the stack.
Before the trigger resolved, my opponent removed the naturalist with Leyline Binding.
The game froze, and I timed out. Since it was Game 2 and I lost Game 1, I lost the match.

I am furious about this. This was not a problem for over a year. Suddenly, it's a problem.
