Card changes to adapt to the new Poison mechanic


“Can you fight an enemy that kills you from within?”

– Mortarion

The Death Guard is here! Right as Mortarion’s Legion gathers, ready to assault Terra, they receive an update to their arsenal to make them even more deadly. With their new wargear and toxic concoctions, the effect of their iconic Poison trait has received a major change.

Besides the Death Guard, multiple factions had very limited access to this trait. These cards have also received an update to make them fit the new Poison mechanic. Take a look at all the changes.


Poison now stacks after a Poisonous unit damages another unit in combat. At the start of its controller’s turn, a poisoned unit will receive damage equal to its Poison stacks and then lose a stack of Poison. Poisonous X units apply stacks of Poison equal to X after damaging an enemy.
