This is a deck centered around putting out as many lands as possible in order to buff Multani, Yavimaya's Avatar. This isn't intended to be competitive but if for whatever reason it ends up winning a lot I won't be upset.
The Superstar
Multani, Yavimaya's Avatar is insane to play with, and a real pain to play against if you're unprepared. A body that scales throughout the game without relying on any other creatures, in one of the most easily ramped colors, with an ability that makes him almost unkillable? Sign me up!
The Lands
Multani gets +1/+1 for every land you control and every land in your graveyard. Because of this, we have an extremely high number of lands in this deck. Evolving Wilds has a very effective interaction with Multani, allowing you to search for a basic and toss a land into your graveyard, perma-buffing Multani +2/+2. Sunpetal Grove is just too good to pass up. Since we're typically going to have a lot of mana untapped between turns, I thought Arch of Orazca was a natural fit here.
The Accelerators
Llanowar Elves do what they do. Wayward Swordtooth is a highly important card to the deck. He helps to pull extra lands from your hand in the early game in order to allow for Multani to drop on turn 3 in conjunction with elves if you're lucky. But another great interaction, one I would argue is the most important one here, is that since he allows for a second land drop every turn, you can return Multani from your graveyard to your hand for free in case he dies somehow. Tatyova, Benthic Druid is great. She can be cast as early as turn 3, and gives us 1 life and 1 card for every land we play (which, I'm not sure if you caught on yet, but we tend to do that a lot).
The Utility Spells
Kamahl's Druidic Vow literally pukes out lands to buff Multani, and can also inadvertently put any of our other legendary creatures onto the battlefield. And accidentally giving everything hexproof isn't a bad thing. If you hit Multani with an early Druidic Vow it isn't a terrible thing either because you can fetch him at any time and he's safe from a vast majority of removal. Enter the Unknown keeps us drawing cards and/or growing our board. And finally, Rishkar's Expertise is amazing in this deck with almost all of our creatures.
The Utility Creatures
Shalai, Voice of Plenty keeps Multani safe from removal and she can also help buff the other creatures you have on the battlefield already with her green ability. She, Multani, and Tatyova can all turn on Kamahl's Druidic Vow. Jadelight Ranger is in here because more than likely, we're going to be drawing cards when we explore.
