An epic farewell: double-faction event!

"Your blind fealty will be your undoing, brother."
– Horus

New double-faction event! With the shadows of treachery looming on the Imperium, three Primarchs stand against their so-called brothers on Isstvan V as a containing wall before rebellion spreads through the Galaxy.

Choose a Warlord and a supporting faction to build a deck like no other! Combine the strength of two factions in a single deck to unlock never-before-seen synergies and dominate the battlefield!
