Land creatures you control have flying.
Whenever a land you control enters, if you control seven or more lands, up to one target land you control becomes a 3/3 Elemental creature with haste. It's still a land.
Tatyova animates your lands into evasive 3/3 hasty Elementals once you hit seven lands, then beats down with a flying army of manlands and animated basics. You ramp aggressively early, deploy land-animation effects, and turn your mana base into a resilient, hard-to-block board that closes games while still functioning as lands.
Add fast mana and ramp (Cultivate, Three Visits, Nature's Lore) plus land-recursion engines like Crucible of Worlds and Ramunap Excavator to keep lands flowing. Layer in mass-animation and anthem effects (Nissa, Who Shakes the World; Craterhoof Behemoth; Kamahl, Heart of Krosa) to convert your mana base into lethal damage in one turn. Improve interaction with cheap counterspells and protect your board against wraths using Heroic Intervention and Teferi's Protection.
