Two Primarchs join the battle

"Death is coming!"
– Mortarion

Event reinforcements! The loyalist forces have been able to resist the traitor tide so far, but the Death Guard returns with their full strength after Mortarion joins them in battle. Feeling the toxic presence of his own brother, the Khan takes to the battlefield to contain the rot.

Mortarion and Jaghatai join the event as reinforcements. Take this opportunity to test the new cards in battle and decide which cosmetic will become collectable at the end of the event.

Which side will you join?
