Five colors, one real plan, no expensive staples.
Make a pile of token bodies, turn those bodies into mana with Niv, then cast the same cheap graveyard spells again for free on upkeep. The mana base is deliberately slow but actually casts a five-color commander; the spells are deliberately cheap but each does more than one job.
How it plays: early turns fix your colors and use cheap looting, self-mill, and token spells. Once Niv is down, your tokens convoke the next spell and your upkeep casts a graveyard instant or sorcery copy for free. The deck doesn’t pretend to be cEDH at twenty bucks; it is a focused budget engine that gets stronger the longer it gets to cast spells.
Price reality: $20.74 is the live item floor for this exact 78-card buy list, combining individual English CardTrader Zero results captured in the recorded source; the timestamp was not preserved. It excludes your owned Niv-Mizzet, Supreme, 21 basic lands, tax, CardTrader Zero fees, and any final cart-assembly changes. No cart has been created. The deck makes Wizards, Spirits, Servos, Goblins, and Fractals—use dice, spare cards, or a free token app rather than buying token cards.
