Ob Nixilis, Unshackled + Field of Ruin + Rings of Brighthearth + Crucible of Worlds

Ob Nixilis, Unshackled

Field of Ruin

Rings of Brighthearth

Crucible of Worlds

How it works

1. Activate Field, targeting a land and triggering Rings of Brighthearth.
2. Pay to copy the Field effect, targeting a different land.
3. Resolve both triggers and the resulting Ob Nixilis triggers, forcing all opponent to lose 20 life.
4. Use Crucible of Worlds to play Field.
5. Repeat steps 1-3.

This ingenious loop turns a simple land destruction effect into a devastating life-draining engine by punishing your opponents for following the rules of the search. When you crack Field of Ruin, Rings of Brighthearth steps in to double the activation—forcing your opponents to search their libraries twice instead of once. Because Ob Nixilis, Unshackled treats each of those mandatory searches as an unforgivable offense, the unfortunate player must sacrifice two creatures and shed a massive 20 life in the process. Finally, Crucible of Worlds ensures that Field of Ruin never truly leaves you, allowing you to replay the land from your graveyard and repeat the carnage turn after turn until everyone else has fallen.
