Ramp

Ramp is purposefully increasing the amount of mana available to you, above that generated by playing one land (that taps for a single mana) per turn.

Description
A deck that ramps may play creatures that tap for mana, cards that allow you to play extra lands, and lands that tap for multiple mana, for example. The strategy is named after the card Rampant Growth.

A Ramp deck accelerates the ability to play high impact, high cost spells early on in the game. Whereas in older format this took the form of fatties, modern magic circa 2018 made this more about planeswalkers or big instants or sorceries.

Colors
Ramp usually appears in green or colorless (e.g. Urzatron lands). Starting in 2021, white is also getting more ramp to help solve its problems in Commander. This can take the form of "catch-up ramp" (giving you a land as your opponent has more lands than you), of "suntide effects" (reanimating lands from the graveyard) or treasure production.
