Mono-Green Titan Ramp

A mono-green ramp deck that uses mana creatures and land-search effects to accelerate into enormous Dinosaurs, Hydras, and Gods ahead of schedule.

Tender Wildguide and Enduring Vitality accelerate your mana while Case of the Locked Hothouse finds lands and later generates extra mana. Freestrider Lookout and Jadelight Spelunker turn land drops into card advantage, and Mossborn Hydra grows from every landfall. Outcaster Trailblazer triggers when four-power creatures arrive, and Ojer Kaslem, Deepest Growth can cheat lands from the top of your library when it deals combat damage.

Keep hands with two to four lands and at least one cheap ramp or land-search effect such as Tender Wildguide, Jadelight Spelunker, or Case of the Locked Hothouse. Mulligan hands that are all five- and six-mana spells or lack green mana.

Early: deploy Tender Wildguide, Valley Mightcaller, and Jadelight Spelunker to build mana and draw cards. Mid: resolve Case of the Locked Hothouse, Enduring Vitality, and Overlord of the Hauntwoods to ramp further while Mossborn Hydra grows huge. Late: cast Agonasaur Rex and Ojer Kaslem to dominate combat and close the game.

Struggles against fast aggro before blockers arrive and is vulnerable to board wipes after committing multiple threats. Countermagic can disrupt key ramp spells unless you have a steady stream of threats, and graveyard removal can interfere with Ojer Kaslem's recursion.
