Namor the Sub-Mariner + Phyrexian Altar + Mystic Speculation + Heliod, the Radiant Dawn // Heliod, the Warped Eclipse

Namor the Sub-Mariner

Phyrexian Altar

Mystic Speculation

Heliod, the Radiant Dawn // Heliod, the Warped Eclipse

How it works

1. Cast Mystic Speculation by paying due to Heliod
2. Namor triggers, creating a 1/1 Merfolk creature token.
3. Resolve Mystic Speculation.
4. Activate Phyrexian Altar by sacrificing the Merfolk, adding .
5. Repeat.

This clever loop revolves around casting Mystic Speculation repeatedly for a single blue mana, a cost reduced to absolute nothingness thanks to the cost-reduction and flash-granting static ability of Heliod, the Radiant Dawn // Heliod, the Warped Eclipse. As you continuously cast the spell, Namor the Sub-Mariner swoops in to trigger off those blue mana symbols, flooding your board with 1/1 Merfolk tokens. You can then feed those very same tokens right into Phyrexian Altar to generate the exact blue mana you need to keep paying for Mystic Speculation's buyback, turning a simple scry spell into an engine for infinite sacrifices and storm count.
