Teshar, Ancestor's Apostle + Salvager of Ruin + Memnite + Yahenni, Undying Partisan

Teshar, Ancestor's Apostle

Salvager of Ruin

Memnite

Yahenni, Undying Partisan

How it works

1. Activate Yahenni by sacrificing Memnite.
2. Activate Salvager of Ruin by sacrificing it, returning Memnite from your graveyard to your hand.
3. Cast Memnite by paying 0.
4. Teshar triggers, returning Salvager of Ruin from your graveyard to the battlefield.
5. Repeat.

This elegant loop is anchored by Teshar, Ancestor's Apostle, whose flying and historic-spell triggers serve as the engine that pulls our fallen artifacts right back from the graveyard. We kick things off by feeding Memnite to Yahenni, Undying Partisan, whose sacrifice outlet not only grows its own power with +1/+1 counters but sends the tiny automaton straight to the graveyard. That fuels Salvager of Ruin's activated ability, letting us sacrifice it to pull Memnite right back to our hand. Once Memnite is recast for free, Teshar's trigger resurrects Salvager of Ruin to the battlefield, perfectly resetting the loop for infinite artifact and creature triggers alike.
