As an additional cost to cast this spell, you may sacrifice any number of artifacts and/or creatures. This spell costs less to cast for each permanent sacrificed this way and less to cast for each other artifact or creature you've sacrificed this turn.
Trample
Partner (You can have two commanders if both have partner.)
Dargo is a cheap, hard-hitting 7/5 trampler you cast by sacrificing chaff—tokens, treasures, expendable artifacts—often for as little as one mana. You flood the board with disposable bodies and artifacts, throw them under Dargo to deploy him early and repeatedly, then beat down or pivot into a sacrifice/aristocrats engine. As a Partner, he pairs with a second commander to add color, card advantage, or a combo angle.
Extremely cheap to recast after removal since sacrifice fodder reduces his cost—great commander-tax resilience
Turns tokens, Treasures, and dying creatures into value, synergizing with aristocrats and sacrifice payoffs
Partner gives huge deckbuilding flexibility to splash a second color or strategy
A 7/5 trampler closes games fast and pushes damage through chump blockers
Mono-red (without a partner) is light on card draw and interaction
Vulnerable to board wipes that erase your sacrifice fodder and tempo
Doesn't generate card advantage on his own—he just hits
Needs a steady stream of fodder; a stalled board makes him expensive and weak
Drains opponents whenever artifacts enter, monetizing Treasure and token swarms.
Add fast mana and sacrifice payoffs—Sol Ring, Dockside Extortionist, Pitiless Plunderer, and Goblin Bombardment—so Dargo lands turn after turn for near-free. Choose a Partner that covers red's weaknesses: a blue partner (Sakashima, Krark, Toggo) adds card advantage and combo potential. Prioritize free sacrifice outlets and aristocrats drains to ensure your fodder generates value beyond just discounting Dargo, and include cheap protection like Lightning Greaves to keep him swinging.
