Signal Pest pumps your entire attacking team for one mana — the kind of overperformer that closes games people thought were still in progress. In non-Human artifact-creature shells like Winota, Joiner of Forces, it pulls double duty as a cheap non-Human trigger and a lord that makes every swing hit harder.
Best Commanders
Commanders with the highest synergy
Winota, Joiner of Forces
Signal Pest is a one-mana non-Human that attacks to trigger Winota, Joiner of Forces, and the battle cry bonus means every Human Winota cheats into play also benefits from a larger team-wide pump — the synergy is structural, not incidental.
Graaz, Unstoppable Juggernaut
Graaz, Unstoppable Juggernaut turns every creature into a Juggernaut, and Signal Pest's battle cry stacks directly on top of that baseline — a one-mana artifact that makes a board of 5/3s hit as 6/3s is exactly the redundant pressure this deck wants.

In Commander, Signal Pest earns its slot in any artifact-creature or wide-attack shell — battle cry scales with board width, so the more attackers you have, the more damage it adds for free. In Modern and Legacy, it has a proven record in Affinity and Hardened Scales strategies, where a one-mana lord that dodges ground combat through flying is a genuine threat rather than a support piece. Vintage contains it but doesn't need it; the format's broken mana makes the one-drop redundant next to more powerful payoffs. Signal Pest has no path into Pioneer, Standard, or Pauper, so outside of Commander its home is firmly in the older constructed formats where artifact synergies are deepest.

Price Context
Current price
$0.36 bulk tier
At $0.36, Signal Pest sits firmly in bulk territory despite consistent competitive play across multiple formats. It's a safe pickup that won't appreciate meaningfully, but at that price point you're just buying a card that does its job — no budget math required.
