Oathkeeper, Takeno's Daisho + Skirk Prospector + Bureau Headmaster

Oathkeeper, Takeno's Daisho

Skirk Prospector

Bureau Headmaster

How it works

1. Activate Skirk Prospector by sacrificing the Goblin Samurai, adding .
2. When the Goblin Samurai dies, Oathkeeper triggers, returning the Goblin Samurai from your graveyard to the battlefield.
3. Activate Oathkeeper's equip ability by paying 1 due to Bureau Headmaster, attaching it to the Goblin Samurai.
4. Repeat.

This loop turns a simple Goblin Samurai into a self-sustaining sacrifice engine, feeding an endless stream of death and enter-the-battlefield triggers through Skirk Prospector's mana-generating ability. The secret to sustaining this loop lies in Bureau Headmaster, whose passive cost-reduction makes Oathkeeper, Takeno's Daisho cheap enough to re-equip using the exact red mana generated from the sacrifice. Whenever your creature falls, Oathkeeper steps in to rescue it from the graveyard and bring it straight back to the battlefield, ready to be sacrificed all over again.
