Survey Mechan + Mortuary + Ashnod's Altar + Quintorius, Field Historian + Primal Vigor

Survey Mechan

Mortuary

Ashnod's Altar

Quintorius, Field Historian

Primal Vigor

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. Quintorius 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 intricate loop relies on Mortuary to intercept Survey Mechan the moment it hits the graveyard, neatly recycling it back to the top of your library so you can redraw and recast it. Meanwhile, Ashnod's Altar provides the colorless mana needed to replay the creature by converting the token fallout generated by Quintorius, Field Historian each time Survey Mechan leaves the graveyard. To supercharge this engine, Primal Vigor doubles the resulting Spirit tokens, ensuring you generate a surplus of mana from Ashnod's Altar that easily outpaces the casting cost while raining down infinite damage, card draw, and life.
