Magmatic Galleon + Ghirapur Aether Grid + Xorn

Magmatic Galleon

Ghirapur Aether Grid

Xorn

How it works

1. Give an opponent's creature indestructible, if needed.
2. Activate Ghirapur Aether Grid by tapping two artifacts you control, dealing 1 damage to an indestructible creature an opponent controls.
3. If the creature has less than 0 toughness, Magmatic Galleon's second ability triggers, creating two Treasure artifact tokens.
4. Repeat from step 2.

This delightful setup turns Ghirapur Aether Grid into a lethal damage-dealing engine by turning Magmatic Galleon's passive replacement trigger into a treasure factory. Every time you tap down artifacts to ping an indestructible opponent's creature, that excess noncombat damage triggers the Galleon to churn out riches, amplified further by Xorn's replacement effect ensuring a net gain of tokens. Because Xorn and Magmatic Galleon feed right back into the tapped artifact requirements of Ghirapur Aether Grid, you can loop this process indefinitely to flood the board with infinite tapped Treasure tokens and endless artifact entries.
