Mordekaiser: revive entries and a durable death engine

Mordekaiser wants early sacrifice-and-revive play and the deployment discount from Disciple of Shadows. The important change in approach is to use useful early allies and a support champion as an engine, rather than waiting with an empty board for Mordekaiser.

Disciple of Shadows

I cost 1 less for each ally in play.
Play: Deal 3 to all other allies.

Bodies on your board reduce the champion cost. Its play damage can also kill disposable allies; account for that damage before sacrificing units you need to retain.

Guardian Angel

+0|+2 and Deathless.
Start adventures with +2 Revives.

Deathless helps preserve a champion entry after a death and the adventure revives add recovery options. The revived champion is not automatically safe from subsequent removal.

Voidborne Carapace

Evolve. When ANY unit dies, grant me its keywords.

Keywords from dying units help the champion scale into a payoff. The slot needs deaths to occur before its keyword collection contributes.

Develop disposable allies before playing Mordekaiser so the entry discount is active. Its play damage can kill bodies, advancing the death engine, but do not sacrifice a key blocker without a recovery plan. Deathless provides another champion entry after a death, while keyword collection helps revived bodies retain useful combat properties.

Use the generated Indestructible tools to protect and revive a meaningful target. Track the champion’s death-based level-up; high-power allied deaths contribute more than small ones according to his current card text. Capture and Obliterate can bypass death triggers, so keep an answer for those effects.

Keep Death's Grasp when an early enemy champion must be removed, and keep an expendable ally to pay its sacrifice. Mist's Call and Chronicler of Ruin help restore or duplicate an important target. Save Indestructible for a unit you actually want to preserve or cycle. A Deathless unit returns Stun with one health, so that alone does not make it an immediate sturdy blocker against Overwhelm.

Corrupted Star Fragment is the main discussed swap. With Mordekaiser's slay-and-revive effect active, its support sacrifice can restore the consumed ally while granting Mordekaiser its stats and keywords. Leave board space for Deathless and revive effects: extra copies can fill the board and prevent the intended unit from returning.

There used to be a repeatable Guardian Angel interaction. It now grants Deathless instead, so use it as protection, not as an infinite loop. Draft cheap useful bodies, removal and revival, then cut cards that do not serve that plan. The leveled champion's attack starts the lasting slay-Drain effect, so level-up alone is not the same as having activated it.

Twice Slain II

Round Start: Create a 2 cost Indestructible in hand or if you have one, reduce its cost by 1.
