Survey Mechan + Mortuary + Ashnod's Altar + Primal Vigor + Teval, the Balanced Scale

Survey Mechan

Mortuary

Ashnod's Altar

Primal Vigor

Teval, the Balanced Scale

How it works

1. Activate Survey Mechan by sacrificing it.
2. When Survey Mechan dies, Mortuary triggers, putting Survey Mechan from your graveyard onto the top of your library.
3. Teval triggers, creating two creature tokens.
4. Resolve the Survey Mechan ability, dealing 3 damage to any target and causing you to draw three cards and gain 3 life.
5. Activate Ashnod's Altar twice by sacrificing the two creature tokens, adding CCCC.
6. Cast Survey Mechan by paying 4.
7. Repeat.

This clever loop revolves around sacrificing **Survey Mechan** to Ashnod's Altar, generating the mana needed to recast it while triggering Mortuary to place it right back on top of your library where it can be immediately drawn. As **Survey Mechan** dies and changes zones, its graveyard departure triggers **Teval, the Balanced Scale** to churn out creature tokens, a process dramatically amplified by Primal Vigor doubling the token output. Those extra tokens are then sacrificed to **Ashnod's Altar** to sustain the mana loop, letting you repeatedly reap **Survey Mechan**'s card draw, life gain, and direct damage until the table is overwhelmed.
