This thought just came to mind after playing a game this morning. I had someone block up their scarabs in a perfect 2x4 block next to a great piece of cover knowing full well I was playing a mordrak list with a warp rift libby.
Came in turn 1 with no scatter, templated all 8 of them off of the board. Tears wept, etc.
What are some examples of some deployment you've either seen or done that just makes you go... seriously?
