Looks really nice! If you're looking to keep playing with a low budget, Polis Crusher is your best friend!

I would also advise to play Evolving Wilds instead of any duallands that come in tapped.

While playtesting I found that I often was manaflooded after turn 4-5. I never have that problem myself because of the monstrous creatures i'm running. I would appreciate it if you gave my deck a look too. My Temur Owned

Evolving wilds does let you mana fix but the land comes in tapped, and at that point I'd rather have the extra life from a dual land.

I know nothing about modern haha, but I will say that looking at the deck and the maybeboard, I don't love Roar of Challenge and I do love Cream of the Crop. Also, I think it might be nice to run something like Nylea, God of the Hunt to give everything trample, since you've got 4x Shaman of the Great Hunt. I'd consider cutting one of the Mob Rules for it -- that seems like more of a 1-of card to me. And Huntmaster of the Fells  ^Flip would be a really clever combo with Cream of the Crop, if you decided to put that in.
