Activate Viscera Seer by sacrificing Crimson Kobolds.
When Crimson Kobolds dies, Mortuary and Remembrance trigger.
Resolve the Mortuary trigger, putting Crimson Kobolds from your graveyard on top of your library.
Resolve the Remembrance trigger, searching your library for Crimson Kobolds and putting it into your hand.
Resolve the Viscera Seer ability, causing you to scry 1.
Cast Crimson Kobolds by paying 0.
Repeat.
This loop relies entirely on Crimson Kobolds costing zero mana, allowing you to recast it endlessly once it hits your hand. Viscera Seer provides the necessary sacrifice outlet to send the Kobolds to the graveyard, triggering both Mortuary to place the creature back on top of your library and Remembrance to tutor another copy straight to your hand. Because you can always cast the Kobolds again for free, this simple setup generates an endless cascade of enters-the-battlefield, leaves-the-battlefield, and death triggers while fueling Viscera Seer's scry ability indefinitely.
