Syr Konrad, the Grim + Relentless Rats + Secret Salvage + Tormod's Crypt

Syr Konrad, the Grim

Relentless Rats

Secret Salvage

Tormod's Crypt

How it works

1. Cast Secret Salvage by paying 3, exiling Relentless Rats from your graveyard and causing you to search your library for all copies of Relentless Rats in your library and put them into your hand.
2. Syr Konrad triggers, dealing 1 damage to each opponent.
3. Move to your cleanup step, causing you to discard down to your maximum hand size, ensuring to discard as many copies of Relentless Rats as possible.
4. Syr Konrad triggers for each creature card discarded this way, dealing that much damage to each opponent.
5. Activate Tormod's Crypt by tapping and sacrificing it, exiling your graveyard.
6. Syr Konrad triggers for each creature card exiled this way, dealing that much damage to each opponent.

This lethal loop revolves around filling your graveyard with a swarm of Relentless Rats and leveraging Secret Salvage to pull every remaining copy from your library straight into your hand. During your cleanup step, discarding that massive horde directly to your graveyard triggers Syr Konrad, the Grim, who gleefully ping-pings your opponents for every single rat that hits the bin. Finally, you can use Tormod's Crypt to instantly exile your graveyard, squeezing even more lethal pings out of Syr Konrad as those cards leave your graveyard.
