[20] On each player's turn, following a set phase order, they draw a card, tap their lands and other permanents as necessary to gain mana to cast spells, engage their creatures in a single attack round against their opponent who may use their own creatures to block the attack, and then complete other actions with any remaining mana

MTGs gameplay loop continues with each player trading turns, buffing up their creatures, and casting spells

Kolodin, Triumph Caster turns Vehicles like Rover Blades and Parhelion II into hasty artifact creatures when they enter the battlefield

Since the goal is triggering landfall not necessarily having a lot of lands dont be afraid to include ramp spells that require you to sacrifice lands, like Harrow and Crop Rotation
