Food For Thought: Dealing with Deathstars
Some are big. Some are expensive. Some even dish out a ridiculous amount of damage. If you pick the right one, it can soak up a massive amount of damage too while it eats through an opposing army.
Deathstars. These uber units of doom can be found in many lists, but creating and using them effectively can be very difficult against a prepared opponent. Typical examples include Draigowing, Fate-crusher, nob bikers, thunderwolves and seer councils on jet bikes. This list goes on, but hopefully you get the idea.
So to help when playing against these super-killy units, I suggest reading Nikephoros' post Back to Basics: Dealing with Deathstars on 3++ is the new black. This really helped me early on, and is another reason I consider mobility and MSU when making my lists. Enjoy!
