What it does
"Tiered" isn't an official Magic keyword or ability—you won't find it in the comprehensive rules. It's likely a confusion with a similar-sounding mechanic, or informal slang players use to describe spells with escalating effects based on how much mana you pay.
The closest official mechanics are "Spree" (from Outlaws of Thunder Junction), where you choose one or more additional modes by paying extra costs, and the older "kicker"/"multikicker" abilities that let you pay more for bigger effects. There's also "tiered" used casually to rank deck power levels (cEDH vs. casual "tiers").
If you encountered "Tiered" on a specific card or in conversation, double-check the exact wording—it may be a custom/unofficial card or a misremembered term. For accurate rulings in Commander, always reference the card's printed Oracle text via Gatherer or Scryfall rather than relying on the nickname.
