land hoooo

Your choice of land search doesn't quite fit the creatures that care about it. You want to use cards that put at least some of the lands straight onto the battlefield, like Nissa's Pilgrimage. Explosive Vegetation is another one you should play. Here are my reasons why the ones you've chosen aren't good:

Firstly, Loam Larva is possibly the worst choice in land search. Not only does it not put the land onto the battlefield, it doesn't even put it into your hand. Additionally, because it puts the land on top of your library, it screws up your draws. I'd replace it with Leaf Gilder, which helps you play a lot of your other cards a turn earlier.
Next, Sylvan Scrying. Don't get me wrong, this is a great card, but because it puts the land into your hand, it's not optimal. Remember you want the lands to enter the battlefield asap. to activate all the juicy landfall triggers.
Lastly, Natural Connection is only good because it's an instant, but because Nissa's Pilgrimage and Explosive Vegetation fetch multiple lands while this only fetches one, it's the third card I'd look at swapping out.

Also, because you only really have one way to give Baloth Pup a +1/+1 counter (Retreat to Kazandu), it's not helping your strategy.
