Roboute Guilliman Deck - January 2026 (Replays + Analysis)

Horus Heresy Legions ranked gameplay featuring Roboute Guilliman, primarch of the Ultramarines.

New month, new year, new poll! I asked YOU which Ultramarine warlord you wanted to see, and the result was pretty clear! Big Gman himself.

The deck in this video is a slower paced control strategy, aiming to drag your opponent into a war of attrition. We then aim to win said war of attrition due to our Mission reward, supplying us with infinite bodies. All we need to do is control the board and survive until we get there. And Guilliman is perfectly suited to do exactly that, his ability can stun an enemy troop and his Reckoning is not just a Heal 5 to your warlord but also puts into play a free Frontline unit on top. This toolkit is destined to be used as a control warlord.

The games in this video were all played right outside High Terra at around 3700 rating. Many of my opponents were in High Terra as this part of the ladder is generally not as populated, leading to many matches against people further up the ladder. Will Guilliman be able to hold his own in the face of the meta? Lets find out!
