that is a LOT of lands... and all basic???

Look out for Bane of Progress

my advice. cut some of the redundant artifacts.

like, you have trailblazer boots, whisper cloak and prowler's helm(i tend to like trailblazers boots myself --as i personally dislike shroud, and people do play walls sometimes). can probably lose 1 if not 2 of those. I also think things like argentum armor, mage armor, and even things like mardu banner, or animist sword. are sort of pointless. and the...if damage/gain cards artifacts don't do anything to kill people with zurgo. so they're also pointless.

especially considering, you don't have any other creatures, and seem to be lacking, spells(or creatures) that grant additional combat phases. which... if you're going zurgo. you might as well capitalize on.

I'd also add in some tutor. zurgo is great colors for it. might as well be able to find answers when you need them (i'd also say... there's much better mass artifact answers available --or like if you're gonna tap for 5ish mana for by force, you might as well tap that same mana and cast a red spell that blows up everything).

if this is for multiplayer, you'll definitely need some other creatures, or something to protect yourself with on the crack back

I'd cut. 3-5 lands (after fixing the mana base) and maybe 5-10ish artifacts. check edhrec for zurgo to see the key creatures, and spells that add additional combat phases. and maybe to see better alternatives to some of the spells you're running.
