Always happy to see another Multani deck! Love the amount of ramp in your list. Will reconsider that in my own version :). Here are some cards for you to consider:

• Grothama, All-Devouring is another way for you to draw a lot of cards without saccing Multani.
• Overwhelming Stampede and Pathbreaker Ibex are nice ways to convert Multani’s power into a win.
• Nylea, God of the Hunt, Bellowing Tanglewurm, and Akroma's Memorial are additional options to give Multani evasion.
• Crashing Drawbridge and Hall of the Bandit Lord are some nice haste enablers to consider.
• Thought Vessel can also be fitting here. I also run some cheap land tutors such as Crop Rotation to find Reliquary Tower more reliably.

And for basics that show Yavimaya: check the Forests from Urza’s Saga ;).

Hope there are some tips there that you like! Check my list here: Maro Multani, the Elemental of Surprise | V-AFR

Great recommendations all around. I have a few of those already and will try and figure out what to switch out. Grothama was already in the deck before and i was debating putting him back in. Recommendations on cuts? Beast Whisperer is probably the first to go. I could stand to lose a bit of ramp, too, I guess...

Was hoping for some modern borders on the basic lands, but THE ART ON THE URZA'S SAGA ONES. MY GOD. Must order. I'm in love. Lol

;). One of those urza’s saga land arts was used later in core sets. Example: https://scryfall.com/card/10e/380/forest

For cuts, I would look at your land synergy section first. Ashaya for example doesn’t seem to be adding a lot to the deck’s premise. Else I would perhaps swap it in for Life's Legacy or your least favorite ramp piece. Veteran Explorer maybe? Not a lot of ways to sac that yourself and get the ramp when you need it.

Ended up going with this (https://scryfall.com/card/usg/349/forest) and that (https://scryfall.com/card/usg/348/forest) as my new basics. Card Kingdom had enough in stock so that I could grab them all in one package. Am legitimately excited for swapping those out. Picking out basic land art is honestly one of my favorite parts of deckbuilding and finding some that "match" my commander gives me the same feeling as finding a cool combo or synergy. Thanks for the heads up on those!!

Ashaya is for target/all "nonland permanent" protection. Cyclonic Rift and stuff like that. Not something I have to deal with in games here at home, but something I'm sure I'd see in public games. Veteran Explorer is a bit weak, I agree. It was mainly a politics/group hug thing anyway. Debating cutting Spore Frog and Zendikar Resurgent as well due to it's high cost and the fact that Vernal Bloom and Nissa, Who Shakes the World do the same thing but for cheaper (the ramp part, anyway. Not worried about the draw part).

Cards that I have here at home that are probably going in are Thought Vessel (Which I swore was already in the deck lol), Grothama, All-Devouring (again), Crop Rotation and Akroma's Memorial.
