Ramp decks accelerate their mana production beyond the normal pace of playing one land each turn. This can involve additional lands, mana creatures, artifacts, or other effects that let expensive spells arrive earlier than expected.
Kodama's Reach and Three Visits provide reliable land-based acceleration, while cards such as Nyxbloom Ancient magnify an already developed mana base. Ramp is usually a means to an end rather than the win condition itself.
