Hi all this is my first go at a Modern deck it's built off my old u/g infect. there is still no sideboard and I still feel it could be better any help would be good!

-4 wild defiance
-2 livewire lash
(To slow for modern)

+3 {might of old krosa}
+3 {groundswell}

Also
-4 hinterland harbors
-2 forest

+2 {breeding pool}
+4 {misty rainforest}

*this isnt a must but fetchlands are really helpful in modern (being able to thin your deck)
