I will be organising a tournament so played a practise game using Maelstrom of War missions and a battle-forged DE list against an unbound guard list. Got the win, bro! If you want the win with tactical objectives, you've gotta be quick. Dark Eldar have mobility in spades! Definitely going to have an element of unbound vs battle-forged.
Kia Kaha, Dark Eldar players!
