The deck needs more ramp... i'd suggest running a couple of keyrunes, maybe go Jund with the deck, Maw of the Mire has some upside to it and Destroy the Evidence can ensure your opponent is less likely to draw into their next land. Possibly even run Trepanation Blade to keep taking their next land-drops before they draw them too

I had some jund cards ready in my maybe board, i had considered it, however, i dont want to fill the deck with things that don't destroy land. In a scenario where i get none, my deck doesn't really do anything.

I understand your point however, some keyrunes would be useful, maybe more so that some of the 3 drop defenders i have.
