Imotekh the Stormlord + Salvaging Station + Umbral Collar Zealot

Imotekh the Stormlord

Salvaging Station

Umbral Collar Zealot

How it works

1. Activate Umbral Collar Zealot by sacrificing the artifact with mana value 1 or less.
2. Activate Salvaging Station by tapping it, returning the artifact from your graveyard to the battlefield.
3. Imotekh's first ability triggers, creating two 2/2 Necron Warrior artifact creature tokens.
4. When the Necron Warriors enter the battlefield, Salvaging Station triggers twice, untapping Salvaging Station.
5. Repeat.

This brilliant loop turns the graveyard into a revolving door of artifact fodder, centered around Imotekh the Stormlord's ability to flood the board with Necron Warrior tokens whenever artifact cards depart your graveyard. Salvaging Station does the heavy lifting by pulling a cheap noncreature artifact back to the battlefield, which conveniently untaps itself twice whenever those newly minted tokens enter and inevitably perish. To keep the cycle going, Umbral Collar Zealot acts as the sacrificial engine that sends your artifacts back to the graveyard while also letting you surveil through your library. Grand Strategist is even hanging around on board to offer a nice combat buff if you ever decide to point its menace and power boost elsewhere.
