Whenever you cast a Human spell, target instant or sorcery card in your graveyard gains flashback until end of turn. The flashback cost is equal to its mana cost. (You may cast that card from your graveyard for its flashback cost. Then exile it.)
Build a critical mass of Humans, then chain instants and sorceries by casting Human creatures to flashback spells from your graveyard for double value each turn. You curve out cheap Humans early, deploy card advantage and removal engines, and grind opponents out while recasting your best spells over and over.
Tighten the instant/sorcery suite to efficient, low-mana-value spells (Swords to Plowshares, Brainstorm, Counterspell) so flashback costs stay affordable, and add fast mana like Sol Ring and Bant signets. Lean into protection (Heroic Intervention, Teferi's Protection) to keep the commander online, and consider a tribal payoff/finisher such as Coppercoat Vanguard plus a go-wide closer like Craterhoof Behemoth or a recurring extra-turn loop to convert the value engine into actual wins.
