You could also consider going even higher on fetchlands. You likely never need more than 4 actual lands in play, and
Wayward Guide-Beast can return lands back to give you retriggers later if you need them.
I guess with W&6, you have more incentive to have more actual lands, but maybe you should consider
Horizon Canopy or other utility lands to get more out of it?
Especially with Elvish Reclaimer, which I would run more of, you can easily fit in a tiny land toolbox. Ghost Quarter or Field of Ruin seem like either one would be a decent 1-of? I'm not super familiar with Modern, and maybe the Tron matchup is already good?
Bojuka Bog could also be a decent sideboard slot if you ran more Reclaimer's?
I agree with the above poster that Kird Ape and Loam Lion are garbage. You should at the very least be running Goblin Guide over one of them.
I'm not a big fan of the Bushwhackers either, but I don't know enough about Modern to really analyze them properly.
Modern Zoo/Sligh should be just as capable of killing on turn 3 as Legacy Zoo/Sligh. Personally, I'd be looking at trimming some of the Bushwhackers for more burn spells, but that's just me.
